Problems solved by technology

[0005] Therefore, it is an object of the present invention to solve the problem that the brake pedal is hard when traffic jams reach such an extent that operation of the accelerator is unnecessary, to obtain brake negative pressure when using an air conditioner during driving in traffic jams, and thereby improve drivability

Embodiment Construction

[0015] Embodiments of the present invention are described below with reference to the drawings.

[0016] Figure 1 to Figure 5 Examples of the present invention are shown. Such as figure 2 As shown in , the vehicle air conditioner control device according to this embodiment includes: an "input" unit that outputs various detection signals to the control section 2 (also referred to as "ECM"); a "calculation" unit that includes A control section 2 to which various detection signals from an "input" unit are input; and an "output" unit to which a control signal from a "calculation" unit is input. The vehicle air conditioner control device 1 further includes: a creep torque generating portion 3 that generates drive torque for moving the vehicle even when the internal combustion engine (not shown) is in an idling state; an air conditioner 4, which is driven by power generated from an internal combustion engine; and an air conditioner control section 5 which controls the operating...

Abstract

The invention provides an automotive air conditioner control device. A crawling torque generating part is configured to generate a driving torque for moving an automobile even when an internal combustion engine is in an ideal speed state. An air conditioner is configured for being driven by the power which is generated by the internal combustion engine. An air conditioner control part is configured for controlling operation state of the air conditioner. A brake negative-pressure detecting part is configured for detecting negative pressure amount of a brake. When the negative pressure amount of the brake, which is detected by the brake negative-pressure detecting part, is lower than a preset value, and the crawling torque generating part generates the driving torque for making the automobile move through the generated driving torque, the air conditioner control part stops the air conditioner.

Description

technical field [0001] The present invention relates to a vehicle air conditioner control device, in particular to a vehicle air conditioner control device which turns off the air conditioner only when the brake negative pressure is insufficient when the vehicle starts to crawl. Background technique [0002] In vehicles equipped with an air conditioner, in order to solve the problems of hard brake pedal (also called "pedal lock feeling") and insufficient brake pedaling force when the air conditioner is activated, use the brake negative pressure sensor or brake negative pressure switch Insufficient negative pressure in the masterback is detected, and if the vehicle speed is above a predetermined speed, the air conditioner is turned off when the brake is applied. By turning off the air regulator, power is sent back to the engine, which creates brake negative pressure.
