[0071] refer to Figure 4 , Figure 4 It is a schematic flowchart of the second embodiment of a multi-slope starting accelerator control method of the present invention. Based on the above-mentioned first embodiment, before the step S10, the throttle control method for multi-slope start in this embodiment further includes:
[0072] Step S11: Obtain the state information of the opening and closing relay. When the state information of the opening and closing relay is the closed state information, obtain the torque verification information, and judge whether the torque verification information meets the preset verification condition.
[0073]It is easy to understand that when the current state information satisfies the preset anti-skid opening condition, it can be considered that the current state information of the vehicle simultaneously satisfies the three conditions of the slope trigger condition, the road property trigger condition and the vehicle speed trigger condition. At...

The invention belongs to the technical field of automobiles and discloses a multi-gradient starting accelerator control method, device and equipment and a storage medium. The method comprises the following steps that ramp maintenance torque and slip critical torque are determined according to the current gradient curve information; an output accelerator threshold value is determined according to the ramp maintaining torque and the slip critical torque through a preset accelerator algorithm; a slope starting accelerator curve is determined through a preset accelerator algorithm according to the slope maintaining torque and the current slope starting torque; the target accelerator curve information is determined according to the output accelerator threshold value and the slope starting accelerator curve; and multi-gradient starting accelerator control is conducted according to the target accelerator curve information. According to the vehicle anti-skid control method, when the vehicle anti-skid control of hill starting is carried out, the ramp maintaining torque, the slip critical torque and the current slope starting torque are considered, the multiple slope torques are combined, the finally obtained target accelerator curve information is made to adapt to the road condition with the complex slope, and a limitation problem that control is carried out only aiming at a certain slope in the prior art is solved.
Description
technical field [0001] The present invention relates to the technical field of automobiles, in particular to a multi-slope starting accelerator control method, device, equipment and storage medium. 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 slope of t...
