Abstract

The invention discloses an intelligent vehicle controller. The intelligent vehicle controller comprises a micro controller unit, wherein the signal input end of the micro controller unit is connected with a switching signal acquisition circuit unit, an analog signal acquisition circuit unit, a collision signal acquisition circuit unit and a vehicle body inclination signal acquisition circuit unit; the signal output end of the micro controller unit is connected with an output control circuit unit; the output control circuit unit outputs a control signal to an executive mechanism of a vehicle; the micro controller unit communicates with a controller area network (CAN) bus interface circuit unit, a local interconnect network (LIN) bus interface circuit unit and a memory unit; and a power management unit supplies power to the micro controller unit, other units and a vehicle sensor. The vehicle controller has high stability, strong functions, high universality and high anti-interference capability, is low in cost and meets the requirements of different working conditions.

Description

technical field [0001] The invention relates to the field of vehicle overall control, in particular to an intelligent vehicle controller applied to electric vehicles. Background technique [0002] With the development of human society and the advancement of science and technology, automobiles have become a necessary means of transportation for every family to travel. However, environmental and energy issues have become increasingly prominent. To achieve energy conservation and environmental protection, low-carbon emission reduction requirements, the production of new energy vehicles is urgently needed; A cleaner, more environmentally friendly, simple in structure, safe, reliable and extremely humanized means of transportation has become an urgent need for people. However, an intelligent vehicle controller used on a new energy vehicle has not been reported yet. Contents of the invention [0003] The object of the present invention is to provide an intelligent vehicle contr...
