Abstract

The invention provides a wire-controlled multifunctional steering device for an electric drive crawler vehicle, the device includes a support rod connected in rotation with the bracket of the cockpit and a steering rudder connected with the upper end of the support rod; An angle sensor coaxial with it is provided; the upper end of the steering rudder is provided with a man-machine interface communicating with the angle sensor and the vehicle control system. In the technical solution provided by the invention, the man-machine interaction interface on the steering rudder collects the operation of the buttons and the steering information of the angle sensor in the support bar, and transmits them to the vehicle control system; It provides convenience in operation such as adjustment, saves complex mechanical connections, and gets rid of various restrictions of traditional steering systems. It is novel in design, convenient in operation, and high in efficiency.

Description

technical field [0001] The invention relates to a control device for an electric drive crawler vehicle; in particular, it relates to a wire-controlled multifunctional steering control device for an electric drive crawler vehicle. Background technique [0002] With people's increasing concern on environmental pollution and energy shortage, as well as the rapid progress and development of high-power permanent magnet synchronous motors, power electronics technology, and energy storage technology, the application of electric drive vehicles is becoming more and more extensive. Different from the traditional "internal combustion engine-mechanical / hydraulic transmission" vehicle, the steering control device of the electric drive vehicle controls the steering of the vehicle by sending the driver's steering angle collected by the sensor to the vehicle controller through the CAN / FlexRay bus. Due to the cancellation of the steering-related mechanical connections, the steer-by-wire syst...
