Problems solved by technology

[0005] The existing automatic parking system has such shortcomings: in the autonomous parking mode, the steering wheel is in a state of completely autonomous rotation. At this time, the driver judges that a dangerous collision may be about to occur and intentionally operates the steering wheel, or the driver is not in danger. Inadvertent contact with the steering wheel, in both cases, the driver is likely to be injured by the turning of the steering wheel

Abstract

The invention discloses a control device and method for safe switching between parking modes. The control device comprises an angle sensor, a torque sensor, a gear signal detection device, a microprocessor, an LED warning lamp, an EPS motor and a buzzer, wherein signals collected by the angle sensor, signals collected by the torque sensor and signals collected by the gear signal detection device serve as input signals of the microprocessor, and output signals of the microprocessor are transmitted to the LED warning lamp, the EPS motor and the buzzer. When an automobile is in the independent parking mode, the torque sensor judges whether externally-added torque exists or not, and the microprocessor judges whether the independent parking mode needs to be switched to the assistance parking mode or not according to the judgment result of the torque sensor; if switching needs to be carried out, the microprocessor controls the rotating speed of the EPS motor to reduce the rotating speed of a steering wheel, the independent parking mode is safely switched to the assistance parking mode, and the assistance parking mode is carried out until parking is stopped. According to the control device and method for safe switching between the parking modes, the problem that safety accidents are possibly caused due to the fact that a driver touches the steering wheel suddenly in the independent parking mode can be solved.

Description

technical field [0001] The invention relates to an automatic parking system, in particular to a control device and a control method for safely switching parking modes. Background technique [0002] The automatic parking system refers to a system in which the vehicle can automatically park into a space without the driver operating the steering wheel after the system is activated and a valid parking space is found. Its general working process is: the information collection system collects relevant information such as the size of the parking space and the vehicle's own coordinates through sensors, and generates data as the input of the system. The information processing system judges whether the vehicle can automatically park in the parking space based on these data and information. Provided space, and generate a suitable parking reference path and corresponding control instructions, the actuator will automatically park the vehicle into the parking space according to the contro...
