Embodiment Construction

[0035] In the following will be based on Figure 1 to Figure 7One embodiment for carrying out the present invention will be described. In the following description made in this specification, the advancing direction (forward moving direction) of the vehicle is described as the front side (the front side of the vehicle).

[0036] The vehicle of the present embodiment has a so-called idle stop function of automatically stopping the engine when a predetermined stop condition is satisfied while the vehicle is running, and thereafter, automatically restarting the engine when a predetermined start condition is satisfied, thereby Improve fuel efficiency performance and emissions performance. Thus, in this vehicle, the engine is automatically stopped during deceleration or during stop by the brake operation performed by the driver.

[0037] An example of a vehicle having an idle stop function will now be described.

[0038] Such as figure 1 The vehicle shown is a so-called front-...

Abstract

A vehicle control device including a first control unit (55, S12, S13) and a second control unit (55) is provided. The first control unit permits the automatic stop of an engine (12) when a stop condition of the engine (12) is satisfied, and permits the restart of the engine (12) when a restart condition of the engine (12) is satisfied. The second control unit (55, S32, S33) performs first braking control for increasing braking force for wheels (FR, FL, RR, RL) when detecting that the start of the engine (12) is in a bad condition after the restart of the engine (12) is permitted. Then, the second control unit performs second braking control for holding the braking force for the wheels (FR, FL, RR, RL). The first control unit (55, S12, S13, S31, S34) prohibits the restart of the engine (12) during the execution of the first braking control, and permits the restart of the engine (12) during the execution of the second braking control.

Description

technical field [0001] The present invention relates to a vehicle control device and a vehicle control method that allow an engine to automatically stop when an engine stop condition of the vehicle is satisfied and allow the engine to restart when an engine restart condition is satisfied. Background technique [0002] In recent years, the development of a vehicle control device having a so-called idle stop function that automatically stops the engine when the vehicle stops or immediately before stopping and is triggered by The engine is automatically restarted by the driver's starting operation. For example, in the control device for a vehicle described in Patent Document 1, in an engine automatic stop state, restarting of the engine is allowed upon detection of a brake operation performed by the driver, in which brake operation is assisted The negative pressure in the booster / supercharger becomes smaller than a predetermined threshold. The booster is connected to the inta...
