Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The following description is only for demonstration and explanation, and does not limit the present invention in any form.

[0041] Such as figure 1 As shown, the electric vehicle speed control system that can switch between two modes freely includes the original vehicle speed controller, the original vehicle motor controller, and the automatic speed controller. The original car motor controller is connected. The automatic speed controller includes an embedded control system. The automatic speed controller takes the embedded control system as the core, realizes the reasonable switching between the original vehicle speed control signal and the computer control signal, and ensures that the corresponding control signal can be input in the corresponding mode. to the original car motor controller.

[0042] The original vehicle motor controller is...

Abstract

The invention discloses an electric car speed control system with two modes switched freely and an electric car speed control method. An automatic speed controller is additionally installed at the front end of an original speed controller of an electric car. The automatic speed controller is centered on an embedded control system and comprises an electronic switch and the other components. A control signal of an original motor controller of the electric car is from an original car acceleration pedal, a gear switch and a brake pedal. The automatic speed controller and the original motor controller are connected with the original car acceleration pedal, the gear switch and the brake pedal. The computer control signal or the signal of the original car acceleration pedal, the gear switch and the brake pedal or a control signal of a computer is received selectively according to the difference between the manual driving working mode or the computer control working mode. The original car speed control signal and the computer control signal are switched reasonably in the situation that an original car system is not transformed greatly. It can be guaranteed that the corresponding control signals are input to the original motor controller in the corresponding modes.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to an electric vehicle speed control system and method capable of switching between two modes freely. Background technique [0002] The so-called smart car refers to a car that has the ability to plan its own driving route, perceive the surrounding environment, make reasonable decisions based on real-time traffic conditions, and assist or even replace the driver in driving, thereby reducing the driver's labor intensity. Make the vehicle driving process more safe, comfortable and efficient. The low-speed intelligent electric vehicle is a robot that completes the intelligent transformation on the basis of the ordinary electric vehicle platform, installs intelligent equipment, and completes specific functions. It can be widely used in fields such as golf carts, park tour buses, elderly scooters, real estate sightseeing cars, etc., and can play an important role in lar...
