Problems solved by technology

[0005] However, even if the brake pedal is depressed with the position of the shift lever set at the parking position, the driver does not necessarily perform an operation to restart driving afterwards.
On the other hand, in the invention of Patent Document 1, since the internal combustion engine is immediately restarted when the brake pedal depression operation is detected with the position of the shift lever set at the parking position, the Fuel efficiency may deteriorate due to excessive repetition of stopping and starting of the internal combustion engine

Embodiment Construction

[0091] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0092] figure 1 It is a figure which shows the structure of the vehicle V of this embodiment.

[0093] The vehicle V has: an internal combustion engine 1 (hereinafter referred to as "engine 1") that generates driving force for running; The driving force generated by the engine 1 is transmitted to driving wheels, not shown in the figure; the battery unit 3 has a battery 31; Distance control, constant speed driving control; brake system 5, which performs brake control in response to the driver's operation on the brake pedal 51; air conditioning system 6, which controls the temperature in the vehicle interior; seat belt switch 7, which detects whether A seat belt provided on the driver's seat is worn; and an electronic control unit 8 (hereinafter, an abbreviation of "ECU 8" is used) which controls the engine 1 .

[0094] The engine 1 is provided with: an alternator 11...

Abstract

The present invention provides a vehicle including a restart condition in which a brake pedal depression operation is detected in a state where a gear is located in a parking position, and it is possible to prevent the engine from being repeatedly stopped and started. The vehicle (V) has: a TCU (24), which acquires a gear; a brake switch (52), which detects a depression operation of a brake pedal(51); and an ECU (8), which causes the engine to stop automatically when a stop condition is established (1), and the engine (1) will restart automatically when the restart conditions are met. When the engine (1) is automatically stopped and the brake pedal (51) is depressed while the gear is in the parking position, the ECU (8) determines that an automatic restart of the engine (1) is required. And decides the execution timing of the automatic restart as the timing of performing the automatic restart, and the engine (1) is automatically restarted at the execution timing of the automatic restart.

Description

technical field [0001] The present invention relates to vehicles. More specifically, the present invention relates to a vehicle provided with an automatic stop-start device that automatically stops an internal combustion engine when a stop condition is satisfied, and automatically restarts the internal combustion engine when a restart condition is satisfied. Background technique [0002] Many vehicles that run using an internal combustion engine as a power generation source have a so-called idle stop function for suppressing fuel consumption in the internal combustion engine. The idling stop function refers to a function of temporarily stopping the internal combustion engine in response to the establishment of a prescribed automatic stop condition, and then restarting the internal combustion engine in response to the establishment of a prescribed automatic restart condition. [0003] Here, regarding the automatic restart condition, various conditions are proposed so as to a...
