Pull-type motor home following electromagnetic braking system comprehensively considering braking coordination, safety and energy-saving and control method thereof

Abstract

The invention discloses a pull-type motor home following electromagnetic braking system comprehensively considering braking coordination, safety and energy-saving and a control method thereof. A wheelspeed sensor is additionally arranged on a motor home, the slip rate of motor home wheels is obtained by combining with the vehicle speed of a main vehicle, and anti-locking motor home synchronous braking is achieved; an energy recovery motor is additionally arranged between the two wheels of the motor home, a clutch is arranged between a motor output shaft and a wheel connecting axle, when the motor is needed to involve in, the clutch is combined, and when the motor is not needed to work, the clutch is separated; a signal of an accelerometer of the main vehicle is monitored in real time, when the signal is a negative value, the clutch is combined, and the motor starts an energy recovery mode to charge a super capacitor; force stress at hooks is further detected, and when force is compressive stress, an electromagnetic bake is connected into for further braking; and the energy recovery motor can further assist driving, when the accelerometer is a positive value, the force at the hooksis pulling stress, the clutch is combined, and the super capacitor is used for driving the motor to conduct assisted driving of the motor home so as to deal with power shortage of the main vehicle.

Description

technical field [0001] The invention relates to the technical field of braking coordination of a trailer-type caravan, in particular to a following electromagnetic braking system and a control method for a trailer-type caravan with comprehensive consideration of brake coordination, safety and energy saving. Background technique [0002] With the continuous development of the domestic economy and the substantial improvement of people's living standards, the RV will show a huge market potential in China, and the related technologies of the RV braking system are also in urgent need of improvement. Electromagnetic braking system is favored by light-duty towed vehicles due to its flexible layout, fast response characteristics and system transplantation versatility, especially for towed caravan braking systems that are relatively independent of the trailer. [0003] The electromagnetic braking system in the trailer-type RV usually adopts the method of synchronously tracking the br...

AI Technical Summary

Problems solved by technology

When the trailer-type RV is driving on complex road conditions (emergency braking, frequent acceleration and deceleration, slippery road, etc.), at this time, simply using the braking deceleration of the main vehicle as the RV tracking braking target cannot satisfy the braking stability and safety requirements. Reliability and energy saving requirements

[0004] The generation of the braking signal of the electromagnetic brake of the existing trailer-type RV is generally based on the brake pedal signal of the main vehicle, or based on the braking deceleration signal of the main vehicle, so as to perform real-time adjustment of the braking strength of the electromagnetic brake. The above-mentioned adjustment methods exist It is impossible to prevent the wheel locking of the RV, and there is a phenomenon of energy dissipation and loss during the frequent braking of the electromagnetic brake of the RV
