Embodiment 1
[0037] figure 1 It is a flowchart of a redundant braking control method provided by Embodiment 1 of the present invention. This embodiment of the present invention is applicable to the braking of electric vehicles. The method can be executed by a redundant braking control device, which can Implemented in hardware and / or software, see figure 1 , the method may include the following steps:
[0038] Step 101. Determine the deceleration torque of the motor of the vehicle according to the initial speed and initial acceleration of the vehicle.
[0039] Wherein, the initial speed can be the speed when the vehicle is ready to decelerate, the initial acceleration can be the acceleration when the strategy is ready to decelerate, the initial speed and the initial acceleration can be obtained according to the sensors set in the vehicle, and the vehicle motor can be a device that provides power in the vehicle, When the vehicle motor rotates in the forward direction, it can provide the ve...
Embodiment 2
[0051] figure 2It is a flow chart of a redundant braking control method provided by Embodiment 2 of the present invention. The embodiment of the present invention is based on the above-mentioned embodiments of the invention. In the embodiment of the present invention, when the vehicle speed is less than the threshold speed , the deceleration torque of the vehicle motor can be attenuated. Correspondingly, see figure 2 , the method provided by the embodiment of the present invention includes:
[0052] Step 201: Determine the rolling resistance, air resistance and acceleration resistance of the vehicle according to the initial speed and acceleration of the vehicle, and determine the sum of the rolling resistance, the air resistance and the acceleration resistance as a comprehensive resistance.
[0053] Among them, the rolling resistance can be the resistance generated by the rolling of the vehicle tires when the vehicle decelerates, which can be obtained through the resistanc...
Embodiment 3
[0088] Figure 4 It is a schematic structural diagram of a redundant braking control device provided in Embodiment 3 of the present invention, which can execute the redundant braking control method provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method. The device can be implemented by software and / or hardware, and specifically includes: a torque determination module 301 , a motor deceleration module 302 , a pressure determination module 303 and a vacuum pump deceleration module 304 .
[0089] Wherein, the torque determination module 301 is configured to determine the deceleration torque of the motor of the vehicle according to the initial speed and initial acceleration of the vehicle.
[0090] The motor deceleration module 302 is used to control the motor of the vehicle to decelerate the vehicle according to the deceleration torque.
[0091] The pressure determination module 303 is configu...
