Abstract
The invention provides an automatic parking system for an automatically driven automobile, which utilizes the fact that a power-off electromagnet has strong magnetism under the condition of power failure, a spring steel plate slightly deforms under the action of the strong magnetism, and the power-off electromagnet is firmly adsorbed on a brake disc to force the whole automobile to be in a static state. The invention can realize the purpose of automatic parking in automatic driving through the relay control.
Description
Technical Field
The invention relates to the technical field of automobiles, in particular to the field of automatic driving trolleys.
Background
With the development of automatic driving, the vehicle can realize driving, braking, obstacle avoidance and parking under the condition of no human intervention. To achieve this, all devices are required to realize respective functions under the command of the VCU of the automobile brain, and modules which need manual operation on a normal automobile need to be replaced by signal control. For this reason, the object of the present patent is to solve the problem of automatic parking.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the automatic parking system which is simple in system structure and convenient to maintain. In order to achieve the purpose, the invention adopts the following technical scheme:
in one aspect, the present autonomous parking system includes: a power-off electromagnet bracket, a power-off electromagnet and a disc brake disc.
Further, this automated driving parking system, its characterized in that: the power-off electromagnet support is welded on the automobile rear axle half shaft;
further, this lose electric type electro-magnet support, its characterized in that: the support is made of a spring steel plate, can be bent and deformed under the condition of stress, and can be restored to a prototype under the condition of no stress.
Further, this automated driving parking system, its characterized in that: the power-off electromagnet is fixed on the power-off electromagnet support, and the power-off electromagnet is a device which has high magnetism when not electrified and demagnetizes when electrified;
further, this automated driving parking system, its characterized in that: the disc brake disc is fixed on a rear axle shaft of the automobile for the rear axle of the automobile.
Further, this dish brake disc of stopping, its characterized in that: the distance between the disc brake disc and the power-off electromagnet is 1mm, and direct contact is avoided.

Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present invention more apparent, specific embodiments are described in detail below with reference to the accompanying drawings. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.
When the automobile is static and motionless, the speed of the automobile is zero, the VCU sends a parking instruction at the moment, the relay is triggered, the relay is disconnected, the power-off relay is powered off, the power-off electromagnet is strong, the power-off electromagnet support is slightly deformed under the action of magnetic force, and the power-off electromagnet is firmly adsorbed on the brake disc to force the automobile to be in a static state.
When the automobile is converted from a static state to a moving state, the VCU closes the power supply of the relay, the power-off relay loses magnetism under the action of power, the power-off electromagnet is disconnected from the brake pad under the action of restoring force of the spring steel plate, and the automobile can run freely.
