A vehicle start control device

Abstract

The invention discloses a starting control device of a vehicle. The starting control device comprises a storage battery of the vehicle, a permanent magnet starter, a DC / DC current transformer and a selector switch. The permanent magnet starter is connected with the storage battery of the vehicle by the selector switch, an output end of the DC / DC current transformer is connected with the permanent magnet starter, an input end of the DC / DC current transformer is connected with the storage battery of the vehicle by the selector switch, and a mode that the permanent magnet starter is directly powered by the storage battery of the vehicle and a mode that the permanent magnet starter is powered by the storage battery of the vehicle via the DC / DC current transformer can be switched over by the aid of the selector switch. The starting control device has the advantage that the problem of difficulty in cold starting of an engine in a low-temperature environment is solved under the condition that the capacity of a battery of an existing vehicle and the model of a starter are unchanged.

Description

Technical field [0001] The present invention relates to a vehicle starting device, in particular to a power source and a control device for starting a starter of an automobile. Background technique [0002] In winter, especially in the high-cold area, the internal resistance of the battery and the viscosity of the engine oil increase due to the low temperature environment, which makes the engine unable to start smoothly. In just a few months, the drivers who leave early and return late have endless upset. If the driver accidentally starts the engine continuously, it will further reduce the battery energy storage and make it more difficult to start. In severe cases, the starter will be burned. If the battery capacity is increased or a high-power starter is used to cope with the severe cold in winter, the severe cold will cause waste of resources and increase vehicle development costs; in addition, vehicles driving in the south do not need to face low temperature environments, so ...

AI Technical Summary

Problems solved by technology

[0004] The invention mainly solves the technical problems existing in the prior art that the engine cannot be started smoothly due to the increase of the internal resistance of the battery and the increase of the viscosity of the engine oil due to the low-temperature environment in the high-cold region, and provides a vehicle starting control device, which does not change In the case of vehicle battery capacity and starter model, solve the problem of difficult cold start of the engine in a low temperature environment
