Problems solved by technology
[0003] The time-sharing four-wheel drive switches of traditional cars are mostly independent knob switches. This kind of knob switch is not only poor in intuition, but also not conducive to the driver's control, which may cause errors in the control process.

The invention provides a four-wheel drive switching device of a vehicle. The four-wheel drive switching device of the vehicle comprises a vehicle microcontroller, a two-wheel drive high switching module, a four-wheel drive high switching module and a four-wheel drive low switching module, wherein a two-wheel high control end and a four-wheel low control end are arranged on the vehicle microcontroller, the two-wheel drive high switching module comprises a first relay and a first witching unit, the four-wheel drive high switching module comprises a second relay and a second switching unit, and the four-wheel drive low switching module comprises a third relay and a third switching unit. The first witching unit, the second witching unit and the third witching unit are initially in an off-state. When the first switching unit is switched on, the first relay is powered down, so that the two-wheel high control end is grounded; when the second switching unit is switched on, the first relay and the second relay are grounded so as to enable the two-wheel high control end and the four-wheel low control end to be suspended; and when the third switching unit is switched on, the third relay is switched on so as to enable the four-wheel low control end to be grounded.
Description
technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to a four-wheel drive switch device for a vehicle. Background technique [0002] Four-wheel drive means that the vehicle maintains four-wheel drive during the entire driving process. Specifically, the engine output torque is distributed to the front and rear wheels in a fixed ratio. This driving mode can make the vehicle have better off-road and handling performance, but it cannot adjust the torque distribution according to the road conditions, and the fuel consumption is high. The four-wheel drive mode includes part-time four-wheel drive and part-time four-wheel drive (Part-Time4WD), and the driver can manually switch from part-time four-wheel drive to part-time four-wheel drive. Among them, the time-sharing four-wheel drive is controlled by the controller to switch between two-wheel drive and four-wheel drive. On normal roads, the vehicle runs in two-wheel ...
