The embodiment of the invention discloses a method for adjusting an idling driving force. The method is adopted for solving the problem that the whole vehicle energy consumption and the loss of the whole vehicle braking device are increased by the constant idling driving force. The method according to the embodiment of the invention comprises the following steps: acquiring a brake pedal depth signal at current moment; confirming a brake pedal depth lifting mode according to the brake pedal depth signal, and judging whether the brake pedal depth corresponding to the brake pedal depth signal is in a preset depth interval, wherein the preset depth interval is arranged as an open interval; and if yes, adjusting the idling driving force according to the brake pedal depth lifting mode and the brake pedal depth, wherein the brake pedal depth within the preset depth interval is in negative correlation with the idling driving force. The embodiment of the invention also provides a terminal. The idling driving force can be effectively adjusted within the preset depth interval, so that the energy consumption of the whole vehicle under the static state can be reduced and the service life of the whole vehicle braking device can be prolonged.
Description
technical field [0001] The invention relates to the field of vehicle control, in particular to an idle driving force adjustment method and device. Background technique [0002] The idling state refers to a working state when the motor is idling. When the motor is running, if the accelerator pedal is completely released, the motor will be in an idling state. [0003] In real life, the idle speed of the motor should be avoided to be too high or too low. If the idle speed of the motor is too high, it will increase energy consumption and increase the working temperature of the motor, thereby accelerating the wear and tear of the motor. There will be a loud impact sound, which will cause great damage to the car. [0004] Generally speaking, when the vehicle is idling, the driver can control the depth of the brake pedal by braking, and rely solely on the mechanical braking force to offset the idling driving force, so that the vehicle is at a standstill. However, the constant idl...
