Embodiment Construction

[0038] like figure 1 It is a schematic block diagram of the device of the present invention;

[0039] The vehicle controller is divided from the communication level, and there are three types of communication: the first is the UART communication of the universal asynchronous receiving / transmitting device, which realizes the calibration and diagnosis communication of the vehicle controller; the second is the LIN bus and the lighting management system. Communication, the communication speed is relatively slow, and the auxiliary control of the lighting management system is carried out to achieve energy saving and convenience; the third is CAN bus to communicate with the motor controller, solar panel management system, battery management system, and power steering system. The communication speed is very fast. The vehicle controller collects the status of each controller and the driver's intention information, analyzes and coordinates the important control strategies of the vehicle...

Abstract

The invention discloses a vehicle control unit of an electric vehicle; the control unit is an embedded controller based on a singlechip and is provided with 6 interfaces; an accelerator pedal sensor, a brake signal sensor and a working voltage current Hall sensor of the control unit are connected with A / D interfaces; a rotation speed sensor is connected with a PWM interface; an ignition switch, a power failure are connected with an I / O interface; a storage cell management system, a power-assisted steering system, an electric motor controller and a solar cell panel controller are connected with a CAN communication interface by a high-speed CAN bus; a calibration matching and a failure diagnosis are connected with an SC10 communication interface; a light management system is connected with an SCI1 communication interface by a LIN bus; the control unit carries out communication by the bus and accepts, filters and handles the vehicle state.

Description

technical field [0001] The invention relates to a vehicle control system in vehicle control technology, in particular to a vehicle controller for a solar electric vehicle. Background technique [0002] Energy saving and emission reduction is a global trend. Under the policy of energy saving and emission reduction, all countries are studying relevant policy orientations, among which the pollution caused by transportation accounts for the largest proportion. Therefore, in order to meet the needs of the public and meet the government's environmental protection regulations, various "green" new energy concept cars have been released one after another to meet the world trend. At present, manufacturers and research and development units of electric vehicles are the most. Compared with the West, my country's automobile research and development is relatively backward. However, at the 2009 Shanghai International Auto Show, there were as many as 10 domestic pure electric vehicles with ...
