[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0041] As mentioned above, in the current driver takeover strategy for lateral motion control, when the vehicle is driving at high speed, the driver needs to meet two conditions: the hand torque value is greater than the preset value and the hand torque value is maintained for a preset fixed time before taking over the steering wheel. However, at high speeds, unexpected steering is likely to occur. If the hand torque is small, the driver cannot take over. If the hand torque is large, it is easy to hit the hand, resulting in a poor driving experience and safety risks.

[0042] In view of this, an embodiment of the present invention provides a method, apparatus, system, vehicle, and equipment for taking over lateral motion control for autonomous driving. The method includes: obtaining the hand torque applied to the steering wheel, the duration of the hand torque, and the current vehicle speed; determining a corresponding takeover condition based on the current vehicle speed; and controlling the electronic power steering system to exit the lateral motion control function when the hand torque and the duration of the hand torque meet the takeover condition. The method has different takeover conditions at different vehicle speeds, and controls the electronic power steering system to exit the lateral motion control function when the hand torque and the duration of the hand torque meet the takeover condition corresponding to the current vehicle speed, so that the driver can quickly and safely take over steering wheel control under different vehicle speed conditions.

[0043] See also Figure 1 , which is a flow chart of a method for taking over lateral motion control of an autonomous driving system provided by an embodiment of the present invention. This method can be applied to an intelligent driving controller, such as Figure 1 As shown, the method includes:

[0044] S110 : Acquire the hand torque applied to the steering wheel, the duration of the hand torque, and the current vehicle speed.

[0045] In this embodiment, it can be understood that in the automatic driving mode, when the driver does not control the steering wheel, the pressure value collected by the pressure sensor will be lower than the preset pressure threshold. When the pressure value collected by the pressure sensor suddenly increases and is higher than the preset pressure threshold, it indicates that the driver has started to control the current steering wheel. At this time, the torque sensor is immediately enabled to collect the torque input by the driver on the current steering wheel in real time through the torque sensor.

[0046] S120. Determine corresponding takeover conditions according to the current vehicle speed.

[0047] For autonomous driving, lateral control is divided into two scenarios: high-speed driving and low-speed parking. Due to the different motion physical conditions in the two scenarios, different takeover conditions are set for different vehicle speed scenarios.

[0048] The present invention provides a specific implementation of S120, as described in A1-A2:

[0049] In one possible implementation, S120 includes:

[0050] A1: When the current vehicle speed is greater than or equal to the vehicle speed threshold, a first takeover condition is determined; the first takeover condition includes: the integral value of the hand torque over the duration is greater than or equal to the integral threshold.

[0051] When the torque is large enough, the integral value of the hand torque over a shorter duration will be greater than the integral threshold, thereby enabling the driver to take over lateral motion control in a shorter time and avoid hand-slapping.

[0052] A2: When the current vehicle speed is less than the vehicle speed threshold, a second takeover condition is determined; the second takeover condition includes: the hand torque is greater than the torque threshold, and the duration of the hand torque is greater than the time threshold.

[0053] In this embodiment, the vehicle speed threshold is 20 kph. A speed greater than 20 kph is considered a high speed, and a speed less than 20 kph is considered a low speed.

[0054] When the vehicle is traveling at low speed, the steering angle and steering speed required for lateral control are larger than those at high speed, which will generate a larger hand torque. If an equivalent integral strategy is adopted, it will cause frequent exit of lateral control at low speed. Therefore, the hand torque is greater than the torque threshold and the duration of the hand torque is greater than the time threshold as the takeover condition.

[0055] S130: When the hand torque and the duration of the hand torque meet a takeover condition, control the electronic power steering system to exit the lateral motion control function.

[0056] When the Electric Power Steering (EPS) system controls lateral motion, the torque applied to the steering wheel and the duration of the torque are collected. When the torque and duration meet the takeover conditions, it indicates that the driver wants to control the lateral motion. At this time, the electronic power steering system needs to exit the lateral motion control of the vehicle.

[0057] The embodiment of the present invention has different takeover conditions at different vehicle speeds. When the hand torque and the duration of the hand torque meet the takeover conditions corresponding to the current vehicle speed, the electronic power steering system is controlled to exit the lateral motion control function, so that the driver can quickly and safely take over steering wheel control under different vehicle speed conditions.

[0058] In one possible implementation, when the hand torque and the duration of the hand torque meet the takeover condition, controlling the electronic power steering system to exit the lateral motion control function includes:

[0059] When the hand torque and the duration of the hand torque meet the takeover condition, a request to exit lateral control is sent to the electronic power steering system, so that the electronic power steering system exits lateral motion control of the vehicle in response to the request to exit lateral control.

[0060] See also Figure 2 , which is a schematic diagram of an application scenario of an automatic driving lateral motion control takeover method provided by an embodiment of the present invention. Figure 2 As shown, the intelligent driving controller collects hand torque and hand torque duration detected by sensors on the steering wheel. When the current vehicle speed is in the high-speed range, if the first takeover condition is met (i.e., the integral of the hand torque over the duration is greater than an integral threshold), a request to exit lateral control is sent to the electronic power steering system, causing the electronic power steering system to exit lateral control of the vehicle in response to the request. When the current vehicle speed is in the low-speed range, if the second takeover condition is met (i.e., the hand torque is greater than the torque threshold and the duration of the hand torque is greater than a time threshold), a request to exit lateral control is sent to the electronic power steering system, causing the electronic power steering system to exit lateral control of the vehicle in response to the request.

[0061] See also Figure 3 , This figure is a structural diagram of an automatic driving lateral motion control takeover system according to an embodiment of the present invention. Figure 3 As shown, the system includes:

[0062] an acquisition unit 310 for acquiring a hand torque applied to the steering wheel, a duration of the hand torque, and a current vehicle speed;

[0063] A takeover condition determination unit 320 is configured to determine a corresponding takeover condition according to the current vehicle speed;

[0064] The control unit 330 is configured to control the electronic power steering system to exit the lateral motion control function when the hand torque and the duration of the hand torque meet the takeover condition.

[0065] The embodiment of the present invention has different takeover conditions at different vehicle speeds. When the hand torque and the duration of the hand torque meet the takeover conditions corresponding to the current vehicle speed, the electronic power steering system is controlled to exit the lateral motion control function, so that the driver can quickly and safely take over steering wheel control under different vehicle speed conditions.

[0066] In a possible implementation, the takeover condition determination unit 320 is specifically configured to:

[0067] When the current vehicle speed is greater than or equal to the vehicle speed threshold, determining a first takeover condition;

[0068] The first takeover condition includes: an integral value of the hand torque over the duration is greater than or equal to an integral threshold.

[0069] In a possible implementation, the takeover condition determination unit 320 is specifically configured to:

[0070] When the current vehicle speed is less than the vehicle speed threshold, determining the second takeover condition;

[0071] The second takeover condition includes: the hand torque is greater than a torque threshold, and the duration of the hand torque is greater than a time threshold.

[0072] In one possible implementation, the control unit 330 is specifically configured to:

[0073] When the hand torque and the duration of the hand torque meet the takeover condition, a request to exit lateral control is sent to the electronic power steering system, so that the electronic power steering system exits lateral motion control of the vehicle in response to the request to exit lateral control.

[0074] An embodiment of the present invention provides an autonomous driving lateral motion control takeover system, comprising: an intelligent driving controller and an electronic power steering system;

[0075] The electronic power steering system is used to control the lateral movement of the vehicle in the automatic driving state;

[0076] The intelligent driving controller is used to obtain the hand torque applied to the steering wheel, the duration of the hand torque and the current vehicle speed; determine the corresponding takeover condition based on the current vehicle speed; when the hand torque and the duration of the hand torque meet the takeover condition, control the electronic power steering system to exit the lateral motion control function.

[0077] In one possible implementation, the intelligent driving controller is specifically used to: determine a first takeover condition when the current vehicle speed is greater than or equal to a vehicle speed threshold; the first takeover condition includes: the integral value of the hand torque over the duration is greater than or equal to the integral threshold.

[0078] In one possible implementation, the intelligent driving controller is specifically used to: determine a second takeover condition when the current vehicle speed is less than a vehicle speed threshold; the second takeover condition includes: the hand torque is greater than the torque threshold, and the duration of the hand torque is greater than the time threshold.

[0079] In one possible implementation, the intelligent driving controller is specifically used to: when the hand torque and the duration of the hand torque meet the takeover conditions, send a request to exit lateral control to the electronic power steering system, so that the electronic power steering system exits lateral motion control of the vehicle in response to the request to exit lateral control.
