[0003] [Patent Document 1] JP 2020-028155 A [Summary of the invention][Problem to be solved by the invention]

[0004] As already mentioned, the sensor for detecting the actuation amount of the actuating part essentially serves to acquire the actuation amount of the actuating part as information from the control device.

[Embodiment of the invention]

[0008] A preferred embodiment of the present invention will be explained in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values, etc., indicated in the embodiment are merely exemplary descriptions of the invention and are not to be construed as limiting the present invention unless expressly stated otherwise. It should be noted that in the present description and drawings, those elements having substantially the same function and structure are designated by the same reference numerals to avoid repetitive explanations, and those elements not directly related to the present invention are omitted. <Aufbau des Fahrzeugs>

[0009] The structure of the vehicle 1 in an embodiment according to the invention is shown in Fig. 1 described.

[0010] Fig. 1 is a schematic diagram showing the outline structure of the vehicle 1. As in Fig. 1, the vehicle 1 comprises a brake operating part 2, an electric booster 3 and a fluid pressure control unit 4. The brake operating part 2 corresponds to an example of an operating part 20 operated by a driver of the vehicle 1. In addition, as explained below, the vehicle according to the invention is not limited to the example in Fig. 1, but can also be, for example, a vehicle that does not include an electric booster 3.

[0011] The brake actuation part 2 is used to actuate the brakes for braking the vehicle 1. The brake actuation part 2 is actuated by the driver's foot. The brake actuation involves the actuation of the brake actuation part 2 by the driver's foot.

[0012] The electric booster 3 supports the driver's braking force (i.e., the pedal force on the brake operating part 2). Specifically, the electric booster 3 has an electric motor that supports the driver's braking force during braking by controlling the operation of the electric motor.

[0013] The fluid pressure control unit 4 functions to regulate the brake fluid pressure of a wheel cylinder in a brake caliper mounted on each wheel. For example, a pump and a solenoid valve are provided in the oil passage of the fluid pressure control unit 4. By controlling the operation of the pump and the solenoid valve, the brake fluid pressure exerting a braking force on the respective wheel is regulated. The brake fluid pressure generated by the master cylinder in response to the driver's braking operation is supplied to a wheel cylinder via the fluid pressure control unit 4.

[0014] As in Fig. 1, the vehicle 1 comprises a control system 10 which controls the operation of the vehicle 1 by performing a treatment using the actuation quantity of the actuating part 20 operated by the driver (in the example in Fig. 1, the brake actuation part 2). The control system 10 comprises a sensor 11 and a control device 12.

[0015] The sensor 11 detects an actuation quantity of the brake actuation part 2 actuated by the driver of the vehicle 1 (ie, the actuation quantity of the brake actuation) and outputs output information corresponding to the actuation quantity. In the example according to Fig. 1, the sensor 11 is not housed in the electric booster 3, but rather is located outside the electric booster 3. In a vehicle 1 in which the sensor 11 is not housed in the electric booster 3, the position of the sensor 11 is not subject to any particular restrictions and can be located, for example, in the passenger compartment or the engine compartment. However, the sensor 11 can also be housed in the electric booster 3.

[0016] The control device 12 has, among other things, a CPU (Central Processing Unit) as a computing processor, a ROM (Read Only Memory) as a storage element for storing the programs used by the CPU, computing parameters, etc., and a RAM (Random Access Memory) as a storage element for temporarily storing the parameters, etc. that change during the execution of the CPU.

[0017] The functions of the control device 12 can also be distributed across multiple devices, but they can also be executed by a single device. If the functions of the control device 12 are distributed across multiple devices, the devices can also be capable of communicating with each other.

[0018] The control device 12 mainly controls the operation of the electric booster 3. Specifically, the control device 12 controls the braking force assisting force of the electric booster 3 by controlling the operation of the electric motor of the electric booster 3. Such control is performed using the output information from the sensor 11.

[0019] In addition to the processing for controlling the operation of the electric booster 3 (corresponding to the first mode described below), the control device 12 can also execute a processing for deactivating the sleep mode (corresponding to the second mode described below). In the sleep mode, the power consumption of the vehicle 1 is suppressed. For example, if the vehicle 1 is stopped and the state in which no driver operation occurs continues for a certain period of time, the vehicle 1 enters the sleep mode. The above two processings are executed jointly using the sensor 11. Details of the above two processings are provided below. <Betrieb des Steuersystems>

[0020] The operation of the control system 10 in the embodiment of the invention will be described with reference to Fig. 2 to Fig. 4 explained.

[0021] As already mentioned, the control device 12 can execute both the processing for controlling the operation of the electric booster 3 and the processing for deactivating the sleep mode. The control device 12 executes the first mode as the processing for controlling the operation of the electric booster 3, while executing the second mode as the processing for deactivating the sleep mode. The control device 12 can switch between and execute this first mode and this second mode.

[0022] Fig. 2 is a flowchart showing an example of the processing sequence performed by the control device 12. Step S101 in Fig. 2 corresponds to the beginning of the tax flow in Fig. 2.

[0023] Begins in Fig. 2, the control device 12 determines in step S102 whether the sleep mode is currently deactivated.

[0024] If it is determined that the sleep mode is currently deactivated (step S102 / YES), it proceeds to step S103. In step S103, the control device 12 switches the treatment mode to the first mode and returns to step S102. If, however, it is determined that the sleep mode is currently activated (step S102 / NO), it proceeds to step S104. In step S104, the control device 12 switches the treatment mode to the second mode and returns to step S102.

[0025] As mentioned above, the first mode is executed when the sleep mode is momentarily deactivated, whereas the second mode is executed when the sleep mode is momentarily activated. The correspondence between the operation amount and the output information at the sensor 11 in the first mode differs from that in the second mode. Thus, the control device 12 can appropriately execute the first mode and the second mode, respectively.

[0026] Fig. 3 is a diagram showing the correspondence between the operation amount X and the output information Y from the sensor 11 in the first mode. In the first mode, the control device 12 acquires the operation amount X of the brake operating part 2 based on the output information Y from the sensor 11. Then, the control device 12 controls the operation of the electric booster 3 based on the acquired operation amount X of the brake operating part 2. An application force corresponding to the operation amount X is applied as a counterforce to the brake operating part 2. Consequently, the control device 12 controls the electric booster 3 such that the force assisting the brake operation force becomes larger as the operation amount X increases.

[0027] As in Fig. 3, the output information Y in the first mode is information indicating a value correlated with the operation amount X. Specifically, in the first mode, as the operation amount X increases, the output information Y also increases. For example, the output information Y in the first mode indicates the value proportional to the operation amount X. By acquiring the operation amount X from such output information Y, the control device 12 in the first mode can regulate the force assisting the brake operation force from the electric booster 3 according to the operation amount X.

[0028] Fig. 4 is a diagram showing the correspondence between the operation amount X and the output information Y from the sensor 11 in the second mode. In the second mode, the control device 12 deactivates the sleep mode based on the output information Y from the sensor 11. Specifically, the control device 12 determines whether the driver has stepped on the brake operating part 2 based on the output information Y from the sensor 11, and deactivates the sleep mode if it is determined that the driver has stepped on the brake operating part 2.

[0029] As in Fig. As shown in Figure 4, the output information Y in the second mode is information indicating whether the actuation size X is greater than a standard actuation size X0. If in the example in Fig. 4 If the actuation quantity X is smaller than the standard actuation quantity X0, the output information Y assumes the value 0, whereas the output information Y assumes the value 1 if the actuation quantity X is larger than the standard actuation quantity X0. The standard actuation quantity X0 is set to such a small value that it can be determined whether the brake actuation part 2 has been stepped on even if the driver only slightly steps on it. In the second mode, the control device 12 deactivates the sleep mode if the output information Y is information indicating that the actuation quantity X is larger than the standard actuation quantity X0 (in the example in Fig.4 when the output information Y assumes the value 1). In this way, if the sleep mode is currently activated, the driver can easily deactivate the sleep mode by operating the brake actuation part 2 with his foot. If, for example, after deactivating the sleep mode, as already mentioned, the vehicle 1 stops and the state in which no driver operation takes place continues for a certain period of time, the vehicle 1 enters the sleep mode.

[0030] As mentioned above, the control system 10 switches the correspondence between the actuation quantity X and the output information Y from the sensor 11 between the first mode and the second mode. For example, the control device 12 switches the voltage applied to the sensor 11 between the first mode and the second mode. In this way, the sensor 11 can determine whether the control unit 12 is in the first mode or the second mode based on the voltage applied to the sensor 11.

[0031] If it is determined that the treatment mode of the control device 12 is in the first mode, the sensor 11 sets the correspondence relationship between the operation amount X and the output information Y such that the output information Y becomes the information indicating the value correlated with the operation amount X. On the other hand, if it is determined that the treatment mode of the control device 12 is in the second mode, the sensor 11 sets the correspondence relationship between the operation amount X and the output information Y such that the output information Y becomes the information indicating whether the operation amount X is larger than the standard operation amount X0. In this way, the control device 12 can appropriately execute the first mode and the second mode, respectively. <Vorteil des Steuersystems>

[0032] The advantage of the control system 10 in the embodiment of the invention will be explained.

[0033] The control system 10 includes the sensor 11, which detects the operation amount X of the operation part 20 (in the above example, the brake operation part 2) operated by the driver of the vehicle 1 and outputs the output information Y corresponding to the operation amount X, and the control device 12, which can activate the sleep mode to suppress the power consumption of the vehicle 1. Furthermore, the control device 12 switches between and can execute the first mode, which is executed when the sleep mode is currently deactivated and in which the operation amount X is acquired based on the output information Y, and the second mode, which is executed when the sleep mode is currently activated and in which the sleep mode is deactivated based on the output information Y. The correspondence relationship between the operation amount X and the output information Y at the sensor 11 in the first mode is different from that in the second mode.In this way, when the sleep mode is momentarily activated, the driver can easily deactivate the sleep mode by operating the operating part 20, which is used for another purpose when the sleep mode is momentarily deactivated. Consequently, the user experience for the driver can be improved.

[0034] Preferably, the output information Y in the control system 10 in the first mode is information indicating the value correlating with the operation amount X, and the output information Y in the second mode is information indicating whether the operation amount X is greater than the standard operation amount X0. In this way, the control device 12 can appropriately acquire the operation amount X in the first mode and appropriately determine whether the operation part 20 is operated by the driver in the second mode.

[0035] Preferably, the control device 12 in the control system 10 deactivates the sleep mode in the second mode when the output information Y is information indicating that the operation amount X is greater than the standard operation amount X0. In this way, the sleep mode can be appropriately deactivated in the second mode via the driver's operation of the operation part 20 as the trigger.

[0036] Preferably, in the control system 10, the actuating part 20 is the brake actuating part 2, which is used for brake actuation. This allows the driver to easily deactivate the sleep mode by actuating the brake actuating part 2 with their foot if the sleep mode is currently activated.

[0037] Preferably, the control system 10 includes the electric booster 3 that assists the driver's braking operation force, and the control device 12 controls the operation of the electric booster 3 in the first mode based on the operation amount X of the brake operating part 2. In this way, in the first mode, the force assisting the braking operation force from the electric booster 3 can be appropriately regulated based on the operation amount X of the brake operating part 2.

[0038] Preferably, the sensor 11 in the control system 10 is not housed in the electric booster 3, but rather is arranged outside the electric booster 3. In this way, the user-friendliness for the driver in a vehicle 1 in which the sensor 11 is not housed in the electric booster 3 can be improved.

[0039] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it is understood that the present invention is not limited to the aforementioned embodiment, and various examples of modifications and improvements within the scope of the claims also fall within the technical scope of the present invention.

[0040] Although the example in which the operating part 20 whose operation amount X is detected by the sensor 11 is the brake operating part 2 was described above, the operating part 20 whose operation amount X is detected by the sensor 11 may also be an operating part 20 other than the brake operating part 2 (e.g., an operating part 20 manually operated by the driver, etc.). In this case, moreover, the application purpose of the operation amount X acquired in the first mode may also be a purpose other than the purpose described above (ie, the purpose of controlling the operation of the electric booster 3). For example, the application purpose of the operation amount X acquired in the first mode may also be the purpose of controlling the operation of a device other than the electric booster 3.

[0041] Although the example in which the vehicle 1 includes the electric booster 3 was described above, the vehicle 1 may also be without the electric booster 3. In this case, for example, the actuation quantity X acquired in the first mode may be used to control the operation of the fluid pressure control unit 4. Furthermore, the vehicle 1 may also be an internal combustion engine vehicle with only the internal combustion engine as the power source, an electric vehicle with only the electric motor as the power source, or a hybrid vehicle with both the internal combustion engine and the electric motor as power sources.
