A vehicle control system of a pure electric vehicle and its vehicle structure

Abstract

The invention discloses a vehicle control system of a blade electric vehicle and a blade electric vehicle structure. A battery high-voltage insulation detection unit and a high-voltage loop interlocking unit are introduced into a high-voltage safety management module, and a vacuum brake assisting module is set, so that the electricity consumption and safety properties of the vehicle are largely improved. An energy recovery unit is implanted in a drive management system, recoverable energy is generated when the vehicle slides or brakes, the energy utilization rate is largely improved, and the cruising capacity of the vehicle is improved. Meanwhile, the vehicle is driven by a rear axle, a drive motor is connected with the rear axle by directly inserting the motor, an intermediary transmission mechanism is omitted, and the structure is more compact; intermediary losses can also be reduced, and the transmission efficiency is higher. The utilization rate of a battery can be effectively increased, so that the cruising capacity of the vehicle is higher.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control system of a pure electric vehicle and a vehicle structure thereof. Background technique [0002] At present, known common automobiles (gasoline or diesel) all have many deficiencies, such as noise problems during engine operation, exhaust pollution problems, non-renewable energy problems, and future development direction problems of the automobile industry. However, in response to these known problems, many automobile manufacturers have actively responded to the calls of international countries to carry out restructuring, and have achieved certain results. One of them is changing cars to pure electric vehicles. Pure electric vehicles use batteries to provide energy to the motor, and the motor outputs power to drive the vehicle forward. Compared with internal combustion engine vehicles, pure electric vehicles have many advantages of environmental protection ...

AI Technical Summary

Problems solved by technology

When the multi-point insulation performance degradation occurs between the high-voltage circuit and the chassis, it will also cause the heat accumulation effect of the leakage circuit, which may cause an electrical fire in the vehicle

However, in the prior art, the high-voltage safety management is not perfect enough, which leads to the low safety performance of the whole vehicle.

Moreover, the vehicle can generate a certain amount of energy when gliding and braking, but the prior art does not pay enough attention to this energy, and there is no corresponding measure to collect it, which directly causes a waste of available energy.
