Problems solved by technology

This kind of control unit and the vehicle using this kind of control unit have the following disadvantages: 1) There are many cables and the wiring is complicated, which makes the internal layout of the vehicle confusing, it is not easy to dissipate heat, and it is easy to cause signal crosstalk between cables, which increases the unsafe factors of vehicle driving , and the cost is high, and information sharing or control with other vehicles cannot be carried out; 2) The stator coil of the eddy current retarder is directly controlled by the manual gear switch, which is easy to generate a large current impact, and then damage the retarder; 3) There is no temperature protection unit, easy to cause damage due to overheating of the retarder

Abstract

The invention discloses a controller of a current vortex retarder and a control method. The controller comprises a first processing unit, a second processing unit, a power driver and a CAN bus, wherein the first processing unit and the second processing unit are both connected with the CAN bus to ensure that the first processing unit outputs a control signal according to a received operating switch signal, the control signal is sent to the second processing unit through the CAN bus, and the second processing unit controls the on-off time sequence of the stator coil of the current vortex retarder through the power driver. The CAN bus is used for the transportation of data so as to simplify the wiring structure, increase the safety and the reliability for the control of the retarder, realize the real-time communication and display in the work state and realize the information sharing or control between vehicles.

Description

technical field [0001] The invention relates to the field of eddy current retarders, in particular to a controller and a control method of an eddy current retarder used in vehicles. Background technique [0002] For existing vehicles, auxiliary braking is generally performed through an eddy current retarder. The mechanical unit of the eddy current retarder is controlled by the control unit, which receives the operation switch information input by the vehicle driver, and controls the on-off timing of the stator coil according to the switch information. The control unit may also include a speed sensor for collecting vehicle speed, a temperature sensor for collecting the operating temperature of the eddy current retarder, and other electronic devices for feeding back the working status of the vehicle and the eddy current retarder. Devices are connected by cables. This kind of control unit and the vehicle using this kind of control unit have the following disadvantages: 1) The...
