Description
Technical Field
The invention relates to the field of brake control, in particular to a safety distance adjusting platform of an electric automobile.
Background
Braking, also referred to as braking, refers to an action of stopping or slowing down a locomotive, vehicle, other transportation means or machinery, etc. in operation. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, mount a brake shoe, belt or disc adapted to it on the machine base, and make it generate braking moment under the action of external force. The braking device is a mechanical braking device capable of slowing down the vehicle, and is also called a speed reducer. Briefly, the method comprises the following steps: the automobile brake pedal is arranged below the steering wheel, and the brake pedal is stepped on, so that the brake lever is pressed in a linkage way and is transmitted to the brake pad on the brake drum to clamp the brake wheel disc, and the automobile is decelerated or stopped. The manual brake of the automobile is arranged beside a gear and connected with a brake lever. There are also common bicycle brakes which are decelerated by means of rod brakes or disc brake brakes or the like fixed to the frame.
Many brakes are emergency brakes, and attention must be paid to braking skills. As discussed herein, the older vehicles are essentially the same as vehicles without ABS. When the vehicle encounters emergency braking, if the braking force is too large, the tires of the vehicle possibly lock (the tires do not rotate at all), two black braking marks which are pulled long can be frequently seen on a road, namely, the tire and the ground friction marks are left on the road when the vehicle is braked without ABS, the tire does not rotate after locking due to emergency braking, but the tire of the vehicle continuously slides forwards when the tire rubs against the ground due to huge inertia, and the tire and the ground friction strongly cause rubber particles rubbed off the tire to generate a black mark.
At the moment, if the direction is forced to be hit, serious consequences such as deviation sideslip, tail flick, even rollover out of control and the like are often generated. Therefore, when the old vehicle is braked, the old vehicle can be braked by a little or a plurality of feet as far as possible, namely, one or a plurality of feet can be slowed down when the old vehicle is braked, so that the advancing direction of the old vehicle can be effectively controlled while the old vehicle is braked, and the danger is reduced. After the vehicle brakes at critical time and is braked to the bottom, if the vehicle sideslips or flicks the tail, the serious consequences can not be caused by observing the runaway in a cool and quiet way. If possible, the direction must be adjusted by slowing down the brake or brakes, and then pressing the brake hard. In general, for a car without abs braking device, the spot brake can be used almost at any time.
Currently, the vehicle types in front of the vehicle are different, the corresponding hundred kilometers are different in braking time, the extreme environments facing the vehicle are different, if the vehicle is an electric vehicle, the consequences such as collision and fire are more serious, for example, the shorter the corresponding hundred kilometers are, the shorter the braking distance is, the more dangerous the vehicle needs to deal with the environment, the larger the corresponding braking amplitude needs to be executed, and therefore, the longer the safety distance needs to be set to relieve the dangerous driving environment.
