Description

Technical Field

[0001] This invention relates to the technical field of vehicles, and in particular to a vehicle hand force simulation system, a vehicle, and related vehicle control methods, vehicle control devices, and a computer-readable storage medium. Background Technology

[0002] In vehicles with steer-by-wire, a hand force simulator can be deployed in the vehicle to enable the driver to feel information such as the vehicle's dynamic response, road conditions, and steering effort. The hand force simulator can transmit information such as the vehicle's dynamic response, road conditions, and steering effort to the driver through the control of the steering wheel.

[0003] In practical applications, manual force simulators can be implemented using six-phase motors. To achieve redundancy, some of the six-phase motors can be grouped together, while others can be grouped into a separate group. However, since both groups are essentially part of the six-phase system, a malfunction in one group could affect the operation of the other.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] This invention provides a vehicle hand force simulation system, which includes a mechanical friction unit and a motor damping unit. The mechanical friction unit and the motor damping unit are used to establish the frictional force for simulating vehicle hand force and serve as backups for each other in terms of mechanical friction. Compared to achieving redundancy solely based on a six-phase motor, this invention offers better redundancy and can meet the safety requirements of driving scenarios. For details, please refer to... Figure 1 .

[0040] Figure 1 A schematic diagram of a vehicle hand force simulation system according to an embodiment of the present invention is shown; as follows: Figure 1 As shown, the vehicle hand force simulation system 10 may include: a multi-area control unit 110, a mechanical friction unit 120, and a motor damping unit 130; wherein:

[0041] The mechanical friction unit 120 and the motor damping unit 130 are used to establish friction and serve as backups for each other in mechanical friction.

[0042] The multi-zone control unit 110 is used to control the mechanical friction unit 120 and the motor damping unit 130 to achieve the simulation of the vehicle's hand force.

[0043] In this embodiment of the invention, the vehicle hand force simulation system 10 may consist of a multi-area control unit 110 for unified control, and a mechanical friction unit 120 and a motor damping unit 130 for establishing friction and serving as backups for each other in mechanical friction; for example, the motor damping unit 130 may be a three-phase motor, which is cheaper than a six-phase motor, in order to reduce the cost of the system.

[0044] In some feasible embodiments, the mechanical friction unit 120 may consist of an HWA (Hand Wheel actuator) column and a mechanical structure (e.g., a hydraulic damper or a magnetorheological damper) that provides damping. Since the mechanical friction unit 120 is composed of simple mechanical structures (such as friction plates, dampers, etc.), its manufacturing cost is relatively low compared to an electric motor, thus further reducing the cost of implementing hand force simulation in vehicles with steer-by-wire systems.

[0045] In practical applications, the multi-zone control unit 110 can control the mechanical friction unit 120 and the motor damping unit 130 to achieve hand force simulation of the vehicle. Since the mechanical friction unit 120 and the motor damping unit 130 serve as backups for each other in terms of mechanical friction, the multi-zone control unit 110 can control the other unit to establish friction force when one of the units fails, thereby achieving full redundancy hand force simulation.

[0046] In this embodiment of the invention, the vehicle hand force simulation system 10 includes: a multi-region control unit 110, a mechanical friction unit 120, and a motor damping unit 130; wherein: the mechanical friction unit 120 and the motor damping unit 130 are used to establish friction and serve as mechanical friction backups for each other; the multi-region control unit 110 is used to control the mechanical friction unit 120 and the motor damping unit 130 to realize the vehicle hand force simulation. By implementing mechanical friction backup based on two independent systems—the mechanical friction unit and the motor damping unit—a high degree of redundancy in the friction-based hand force simulation can be ensured; compared to redundancy achieved solely based on a six-phase motor, this embodiment of the invention offers better redundancy and can meet the safety requirements of driving scenarios.

[0047] In one embodiment of the present invention, the multi-region control unit 110 integrates a hand force simulation motor drive and hand force simulation software for controlling the mechanical friction unit 120 and the motor damping unit 130.

[0048] In some feasible embodiments, by reusing the MCU (Microcontroller Unit) and power chip in the multi-region control unit 110, the cost of simulating manual force in steer-by-wire vehicles can be further reduced.

[0049] For example, a hand force simulation motor drive can be used as the drive for the motor damping unit 130, and hand force simulation software can be used to control the mechanical friction unit 120. This embodiment of the invention does not limit this.

[0050] In one embodiment of the present invention, the multi-area control unit 110 is also used to control the mechanical friction unit 120 to simulate the hand force of the vehicle when the motor damping unit 130 fails.

[0051] In some feasible embodiments, when the motor damping unit 130 fails, the multi-zone control unit 110 can simulate the hand force of the vehicle by individually controlling the mechanical friction unit 120.

[0052] In other feasible embodiments, the multi-zone control unit 110 can also simulate the hand force of the vehicle by individually controlling the motor damping unit 130 when the mechanical friction unit 120 fails.

[0053] In one embodiment of the present invention, the vehicle hand force simulation system 10 further includes a front wheel actuator and an angle sensor;

[0054] The multi-zone control unit 110 is used to control the front wheel actuator, the mechanical friction unit 120, and / or the motor damping unit 130 based on the data output by the angle sensor.

[0055] In some feasible embodiments, the front wheel actuator can be connected to the vehicle's wheels to control the steering of the vehicle's wheels; angle sensors can be used to detect the steering wheel angle and / or the steering of the wheels, etc., and the embodiments of the present invention do not limit this.

[0056] In practical applications, the angle sensor can be used to output data to the multi-zone control unit 110. This data can be the vehicle's steering angle data, which can be determined based on the steering wheel angle and / or the wheel steering, etc.

[0057] After obtaining the data output by the angle sensor, the multi-zone control unit 110 can control the front wheel actuator according to the data output by the angle sensor to control the steering of the vehicle wheels; the multi-zone control unit 110 can also control the mechanical friction unit 120 and / or the motor damping unit 130 according to the data output by the angle sensor to simulate the hand force of the vehicle.

[0058] In one embodiment of the present invention, the angle sensor includes a torque angle sensor and a steering angle sensor;

[0059] The multi-zone control unit 110 is used to control the front wheel actuators based on data output from the torque angle sensor and / or steering angle sensor.

[0060] In some feasible embodiments, the angle sensor may include a torque angle sensor and a steering angle sensor; wherein, the torque angle sensor (TAS) is a sensor that integrates a torque sensor and an angle sensor, capable of simultaneously measuring the torque applied to the steering wheel by the driver and the steering wheel rotation angle. The steering angle sensor is a sensor specifically designed to measure the steering wheel rotation angle.

[0061] In practical applications, the multi-zone control unit 110 can control the front wheel actuators based on the data output by the torque angle sensor and / or steering angle sensor, so as to control the steering of the vehicle wheels through the front wheel actuators.

[0062] In one embodiment of the present invention, the vehicle hand force simulation system 10 further includes an extended control unit, and the front wheel actuator includes a first front wheel actuator and a second front wheel actuator;

[0063] The multi-zone control unit 110 is connected to the torque angle sensor, the first front wheel actuator, and the extended control unit respectively; the extended control unit is connected to the steering angle sensor and the second front wheel actuator respectively.

[0064] The multi-zone control unit 110 is used to control the first front wheel actuator based on data output by the torque angle sensor and / or the steering angle sensor;

[0065] An extended control unit is used to control the second front wheel actuator based on data output from a torque angle sensor and / or a steering angle sensor.

[0066] In some feasible embodiments, the front wheel actuator may include a first front wheel actuator and a second front wheel actuator to increase the overall redundancy of the vehicle hand force simulation system 10.

[0067] For example, the multi-zone control unit 110 can be connected to the torque angle sensor, the first front wheel actuator, and the extended control unit respectively; specifically, the multi-zone control unit 110 can be connected to the torque angle sensor, the first front wheel actuator, and the extended control unit respectively via PCAN (PEAK-System Controller Area Network). The extended control unit can also be connected to the steering angle sensor and the second front wheel actuator respectively via PCAN.

[0068] In practical applications, the multi-zone control unit 110 can receive data from the torque angle sensor and / or the steering angle sensor, and control the first front wheel actuator based on the data output by the torque angle sensor and / or the steering angle sensor, so as to control the steering of the vehicle wheels through the first front wheel actuator.

[0069] In other feasible embodiments, the extended control unit may also receive data from the torque angle sensor and / or steering angle sensor; specifically, the extended control unit may acquire the data output by the torque angle sensor through the multi-zone control unit 110. After obtaining the data output by the torque angle sensor and / or steering angle sensor, the extended control unit may control the second front wheel actuator based on the data output by the torque angle sensor and / or steering angle sensor, so as to control the steering of the vehicle wheels through the first front wheel actuator.

[0070] For example, the first and second front wheel actuators can be redundant in their control; the torque angle sensor and the steering angle sensor can be redundant in their angle data. For instance, if the multi-zone control unit 110 or the torque angle sensor malfunctions, the extended control unit can control the second front wheel actuator based on the data output by the steering angle sensor. Similarly, if the extended control unit or the steering angle sensor malfunctions, the multi-zone control unit 110 can control the first front wheel actuator based on the data output by the torque angle sensor; this embodiment of the invention does not impose limitations on this.

[0071] In some feasible embodiments, the first front wheel actuator and the second front wheel actuator can communicate via an IMC (Intermediate Module Connector).

[0072] For example, such as Figure 2a As shown: The vehicle hand force simulation system 10 may include MZCU (i.e., multi-zone control unit), XCU (i.e., extended control unit), mechanical friction unit 120 (which may be an HWA column and mechanical damping structure), TAS, HWAMOTOR (three-phase motor (i.e., motor damping unit)), SAS (steering angle sensor), RWA1 (i.e., first front wheel actuator) and RWA2 (i.e., second front wheel actuator).

[0073] The MZCU is equipped with an HWA motor drive and hand force simulation software at the application layer; TAS and SAS are at ASILD (Automotive Safety Integrity Level D); and MPS (Micro Position Sensor) is also installed at TAS.

[0074] The MZCU can be connected to the HWA column, TAS, MPS and three-phase motor respectively. The MZCU can also be connected to the XCU and RWA1 through PCAN1; the XCU can be connected to the SAS and RWA2 through PCAN2; the RWA1 and RWA2 are connected through the IMC; the peak current of the three-phase motor can be set to 80A.

[0075] against Figure 2a As shown in the diagram, the MZCU can receive data output from TAS and MPS, and can control the HWA column, the three-phase motor, and RWA1. The XCU can receive data output from SAS and control RWA2. The MZCU and XCU can also exchange data.

[0076] In one embodiment of the present invention, the multi-region control unit 110 includes a first domain control unit and a second domain control unit, and the front wheel actuator includes a first front wheel actuator and a second front wheel actuator;

[0077] The first domain control unit is connected to the torque angle sensor, the first front wheel actuator, and the second domain control unit; the second domain control unit is connected to the steering angle sensor and the second front wheel actuator.

[0078] The first domain control unit is used to control the first front wheel actuator based on the data output by the torque angle sensor and / or steering angle sensor;

[0079] The second domain control unit is used to control the second front wheel actuator based on data output from the torque angle sensor and / or steering angle sensor.

[0080] In some feasible embodiments, the first domain control unit can be connected to the torque angle sensor, the first front wheel actuator, and the second domain control unit, respectively; the second domain control unit can be connected to the steering angle sensor and the second front wheel actuator, respectively. Specifically, the first domain control unit can be connected to the torque angle sensor, the first front wheel actuator, and the second domain control unit via PCAN (PEAK-System Controller Area Network). The second domain control unit can also be connected to the steering angle sensor and the second front wheel actuator via PCAN.

[0081] In practical applications, the first domain control unit can receive data from the torque angle sensor and / or steering angle sensor, and control the first front wheel actuator based on the data output by the torque angle sensor and / or steering angle sensor, so as to control the steering of the vehicle wheels through the first front wheel actuator.

[0082] In other feasible embodiments, the second domain control unit may also receive data from the torque angle sensor and / or steering angle sensor; specifically, the second domain control unit can acquire the data output by the torque angle sensor through the first domain control unit. After obtaining the data output by the torque angle sensor and / or steering angle sensor, the second domain control unit can control the second front wheel actuator based on the data output by the torque angle sensor and / or steering angle sensor, so as to control the steering of the vehicle wheels through the first front wheel actuator.

[0083] For example, the first and second front wheel actuators can be redundant in their control; the torque angle sensor and the steering angle sensor can be redundant in their angle data. For instance, if the first domain control unit or the torque angle sensor malfunctions, the second domain control unit can control the second front wheel actuator based on the data output by the steering angle sensor. Conversely, if the second domain control unit or the steering angle sensor malfunctions, the first domain control unit can control the first front wheel actuator based on the data output by the torque angle sensor. This embodiment of the invention does not impose any limitations on this.

[0084] like Figure 2b As shown, the vehicle manual force simulation system 10 may include ZCU_A (i.e., the first domain control unit), ZCU_B (i.e., the second domain control unit), HWA column, TAS, three-phase motor, SAS, RWA1 and RWA2.

[0085] ZCU_A contains an HWA motor driver and a hand force simulation software at the application layer; MPS is also set at TAS.

[0086] ZCU_A can be connected to HWA column, TAS, MPS and three-phase motor respectively. ZCU_A can also be connected to ZCU_B and RWA1 through PCAN1; ZCU_B is connected to SAS and RWA2 through PCAN2; RWA1 and RWA2 are connected through IMC; the peak current of the three-phase motor can be set to 80A.

[0087] against Figure 2b As shown in the diagram, ZCU_A can receive data output from TAS and MPS, and can control the HWA column, the three-phase motor, and RWA1. ZCU_B can receive data output from SAS and control RWA2. ZCU_A and ZCU_B can also exchange data.

[0088] Based on the vehicle hand force simulation system described above, this embodiment of the invention also provides a vehicle in which any of the vehicle hand force simulation systems mentioned in the above embodiments can be deployed; in addition, the vehicle may also include wheels and a steering wheel, etc., so as to control the wheels and steering wheel, etc. through the vehicle hand force simulation system.

[0089] Based on the aforementioned vehicle hand force simulation system and / or the aforementioned vehicle, embodiments of the present invention also provide a vehicle control method; this vehicle control method can be applied to the aforementioned vehicle hand force simulation system or vehicle. Specifically, please refer to... Figure 3 , Figure 3 A flowchart illustrating the steps of a vehicle control method according to an embodiment of the present invention is shown.

[0090] like Figure 3 As shown, the vehicle control method may include the following steps:

[0091] Step 301: Obtain the vehicle's steering angle data.

[0092] In practical applications, the vehicle's steering angle data can be obtained first through an angle sensor; specifically, the vehicle's steering angle data can be determined based on the data output by the torque angle sensor, or it can be determined based on the data output by the steering angle sensor. This embodiment of the invention does not limit this.

[0093] Step 302: Based on the steering angle data, control the mechanical friction unit and motor damping unit in the vehicle hand force simulation system.

[0094] After determining the vehicle's steering angle data, the mechanical friction unit and motor damping unit in the vehicle's hand force simulation system can be controlled based on the steering angle data to achieve hand force simulation of the vehicle.

[0095] In this embodiment of the invention, vehicle steering angle data is acquired; based on the steering angle data, the mechanical friction unit and the motor damping unit in the vehicle hand force simulation system are controlled.
