Automobile electronic pump driving control circuit and automobile electronic module

Abstract

The embodiment of the invention discloses an automobile electronic pump driving control circuit and an automobile electronic module. The control circuit comprises a first logic gate, a first level conversion circuit, a first pull-up resistor, a second logic gate, a second level conversion circuit and a second pull-up resistor. And the first level conversion circuit and the second level conversion circuit respectively output a first driving signal and a second driving signal which are completely opposite logically so as to drive the electronic pump to continuously operate. According to the embodiment of the invention, the problem that a user cannot effectively control the electronic pump due to the fact that the electronic pump enters a paralyzed state when an existing vehicle-mounted control system breaks down is solved. Under the working condition that the vehicle-mounted control system breaks down, short-time effective control over the electronic pump can be achieved, and vehicle running and user personal safety risks caused by control failure of the electronic pump can be effectively avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobiles, and in particular, to an automobile electronic pump drive control circuit and an automobile electronic module. Background technique [0002] At present, electronic pumps are widely used in the automotive field. The user controls the electronic pump through the on-board control system, which can effectively realize many functions such as steering, heat dissipation, lubrication and braking of the vehicle. [0003] However, in the prior art, once the vehicle-mounted control system itself fails, for example, the main control chip fails, the electronic pump will enter a paralyzed state accordingly, and the user cannot effectively control the electronic pump. Based on this, when the user's vehicle is in a specific scene such as driving on a steep slope, the failure of the electronic pump control caused by the failure of the on-board control system will seriously threaten ...

Problems solved by technology

[0003] However, in the prior art, once the vehicle-mounted control system itself fails, such as the failure of the main control chip, the electronic pump will enter a paralyzed state accordingly, and the user cannot effectively control the electronic pump.

Based on this, when the user's vehicle is driving on a steep slope and other specific scenarios, the failure of the electronic pump control caused by the failure of the on-board control system will seriously threaten the driving safety of the vehicle and the personal safety of the user.
