The invention provides a vehicle deceleration adjusting method and device.The method comprises the steps that when a vehicle is in a starting state, collecting the speed information of the vehicle under the movement working condition, the brake pressure under the brake working condition and the load size under the load working condition; determining a set current deceleration value of the vehicle; setting a first correction value corresponding to the movement condition based on the speed information; based on the brake pressure, setting a second correction value corresponding to the brake working condition; setting a third correction value corresponding to the load working condition based on the speed information and the load size; calculating the first correction value, the second correction value, the third correction value and the current deceleration value, and obtaining a final deceleration value corresponding to the vehicle; and based on the final deceleration value, adjusting a preset deceleration knob, and completing the current adjustment process of the vehicle deceleration. By applying the method provided by the invention, the correction value for adjusting the deceleration of the vehicle can be set according to each working condition, and the deceleration of the vehicle under each current working condition can be set.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method and device for adjusting vehicle deceleration. Background technique [0002] During the driving process of the vehicle, a fixed deceleration value will be set in the vehicle. When the vehicle needs to decelerate, the vehicle will decelerate and stop according to the set deceleration value. For agricultural vehicles, it includes motion conditions, braking conditions and load conditions. During the driving process of agricultural vehicles, the same deceleration value is used under each condition. [0003] In actual situations, if the farming vehicle is only decelerated and stopped according to the preset deceleration in the farm vehicle, due to the particularity of the road, when the farm vehicle is driving at the end of the farmland, if the deceleration is too small, the vehicle will easily rush out of the farmland, affecting Vehicle safety.
