[0081] refer to Figure 4 , Figure 4 It is a schematic flowchart of the second embodiment of a method for controlling anti-skid at start of a vehicle according to the present invention. Based on the above-mentioned first embodiment, the method for controlling anti-skid at start of the vehicle in the present embodiment includes in the step S30:

[0082] Step S301: Determine the slope maintenance torque and slip critical torque according to the current slope curve information.

[0083] It should be noted that the ECU may also include a ramp torque calculation module. The slope torque calculation module acquires current slope curve information. For example, the slope torque calculation module builds the slope curve and the slope maintenance torque curve according to the current slope curve information within a preset time. The ramp torque calculation module obtains the ramp torque information in the speed control model of the vehicle power domain controller, builds the ramp ...

Abstract

The invention belongs to the technical field of automobile safety and discloses an automobile starting anti-slip control method, device and equipment and a storage medium. The method comprises the following steps of obtaining the current state information of an automobile, and obtaining the current slope curve information when the current state information meets a preset anti-slip starting condition; determining the target accelerator curve information according to the current slope curve information through a preset accelerator algorithm; acquiring the current road environment information, and determining a corresponding accelerator relation table according to the current road environment information; and optimizing the limit value of the target accelerator curve information according to the accelerator relation table, and controlling the torque of the vehicle according to the optimized limit value so as to realize stable ramp starting. According to the method, the current slope curve information is obtained according to the actual ramp working condition before the vehicle is started, the target accelerator curve information of the driver is determined, the target accelerator curve information is optimized according to the current road environment information, stable ramp starting is achieved, the vehicle slipping working condition is effectively avoided, and the method adapts to various types of ramp starting working conditions.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a method, device, equipment and storage medium for controlling antiskid at start of automobiles. Background technique [0002] At present, the existing vehicle controllers in the market generally respond to the driver's torque demand according to the driver's accelerator pedal stepping depth, and control the motor torque output; if the output torque is too large, it will cause the drive wheel to slip , there is no protection and avoidance measures; although the automotive electronic stability control system also has protection measures against wheel slippage, the protection measures are simple, such as directly reducing the motor torque to very low or even zero, which cannot meet the vehicle dynamic performance and driving needs. When the electric vehicle is driving on the slope and needs to stop, the electronic parking system collects the sensor signal, judges the slop...
