Automatic parking method based on ASR system

Abstract

The invention relates to the field of automobile control devices, and provides an automatic parking method based on an ASR system. The method comprises the following steps: S1, monitoring the revolving speed of wheels and the position of a throttle valve through a wheel revolving speed sensor and a throttle valve position sensor of the ASR system, and then executing a step S2; S2, judging whether the conditions that the wheel revolving speed is zero and the throttle valve position is in an idling state are simultaneously met, executing a step S3 if the conditions that the wheel revolving speed is zero and the throttle valve position is in the idling state are simultaneously met, and executing a step S5 if the conditions that the wheel revolving speed is zero and the throttle valve position is in the idling state are not simultaneously met; S3, judging whether the lasted duration at which the wheel revolving speed is zero and the throttle valve position is in the idling state reaches the preset duration through timing by an ECU interior timer, executing a step S4 if the lasted duration at which the wheel revolving speed is zero and the throttle valve position is in the idling state reaches the preset duration, and executing the step S1 if the lasted duration at which the wheel revolving speed is zero and the throttle valve position is in the idling state does not reach the preset duration; S4, starting brake control, and then executing the step S1; and S5, removing the brake control, and then executing the step S1. No additional components are needed to be installed, the original automobile layout structure is not changed, facilities adopted in the method can be shared with the corresponding function components of the ASR antiskid system, and the method can be implemented just through the program updating in an electronic controller ECU, thereby being low in implementation cost.

Description

technical field [0001] The invention relates to the field of automobile control devices and provides an automatic parking method based on an ASR system. Background technique [0002] Drivers who stop and go in the city often cause unnecessary accidents due to paralysis. When the vehicle is temporarily parked on a slope or waiting for a red light, it is generally necessary to engage the P gear. In order to avoid operational troubles, most drivers choose not to shift gears and only step on the brakes. Caused an accident, so the automatic braking system came into being. After starting this function, for example, when stopping and waiting for traffic lights, you don’t need to change gears. This function is also suitable for starting uphill; it reduces the driver’s driving fatigue. It brings great convenience to driving. Therefore automobile automatic braking technology is more and more paid attention to, and for example in the patent document that the Chinese patent applicatio...
