Abstract

The embodiment of the invention provides a driving controller, and belongs to the field of automobiles. The driving controller comprises an electronic control unit; the electronic control unit is provided with an input power supply end P1, an output power supply end P2, an MCU (Microprogrammed Control Unit) and an integrated driving module connected with the MCU; a first power supply input end VS of the integrated driving module is used as the input power supply end P1, and a first power supply output end Vout of the integrated driving module is used as the output power supply end P2; the MCU is used for outputting an on-off control signal to the integrated driving module; and the integrated driving module is used for controlling the on-off between the first power supply input end VS and the first power supply output end Vout according to the on-off control signal. The power semiconductor device is integrated in the ECU, so that the ECU can directly drive the vacuum pump, and the built-in semiconductor switch device is adopted to replace a conventional mechanical contact relay, so that the service life of the integrated driving module is longer.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a drive controller and a drive control circuit of a vacuum pump. Background technique [0002] As a key component of the vehicle braking system, the vacuum pump provides the energy source of the braking system. If the vacuum pump breaks down, the brake will lose boost, and the braking performance will be greatly reduced, which will endanger driving safety. [0003] The existing ECU (Electronic Control Unit) does not have the driving capability of high-power electrical appliances, and usually uses a relay placed in the power distribution box of the front cabin to control the power on and off of the vacuum pump. The frequency of start and stop of the vacuum pump is high, and the contact of the relay sometimes has ablation failure. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a driving controller and a driving control circuit ...
