Vehicle control apparatus
11181086 · 2021-11-23 · ·

A vehicle control apparatus for a vehicle provided with an engine and an electric motor includes a vehicle state evaluator, an exit evaluator, a shutdown evaluator, and a request output unit. The vehicle state evaluator conducts a vehicle stop evaluation and a driving state evaluation on the engine. The vehicle state evaluator evaluates whether the vehicle is stopped in a ready-on state in the vehicle stop evaluation. The exit evaluator conducts an exit evaluation as to whether an exit of an occupant from the vehicle is detected. The shutdown evaluator conducts a shutdown evaluation as to whether a vehicle drive system is to be shut down based on the results of the vehicle stop evaluation, the driving state evaluation, and the exit evaluation. The request output unit outputs a request for shutting down the vehicle drive system based on the result of the shutdown evaluation.

Restarting method and restarting assembly for starting an internal combustion engine of a motor vehicle

The invention relates to a restarting method for automatically starting an internal combustion engine (2) of a motor vehicle (3) by means of a brake pedal actuation, comprising the following steps: detecting a brake pressure (p) by means of a brake pressure sensor (14); emitting a corresponding brake pressure signal sequence to a control device (13); determining a brake pressure profile (p.sub.pr) from the brake pressure signal sequence; determining a reference pressure value (p.sub.R) from the brake pressure profile; detecting a brake release status, wherein, with the release of a brake pedal, a brake pressure decrease (Δp) is detected based on the determined reference pressure value (p.sub.R), with said decrease exceeding a pressure decrease limit value (Δp.sub.G); emitting a starting signal (S.sub.WS) to a starter (15) for starting the internal combustion engine (2), if the brake release status has been detected. The invention also relates to a restarting assembly for a motor vehicle (1) for carrying out a method of this type.

CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

An idling stop control device includes an authenticator, a storage, a getting-off detector, and an engine restart permitter. The authenticator is installed in a vehicle, performs authentication via a wireless communication with a mobile device, and repeatedly performs, while the vehicle travels, an authentication operation at predetermined intervals. The storage stores result and time of authentication as the authentication history during travel. The engine restart permitter determines permission or prohibition of restart of the engine in accordance with the authentication history and getting-off information, permits restart of the engine when the authentication is successful and permits, in a case where the authentication fails, restart of the engine when a history of success of authentication has been stored in the storage during travel and the getting-off is not detected after the authentication has been successful.
