Start/stop system for a motor vehicle drive
First Claim
Patent Images
1. A method for preparing a start/stop system of a motor vehicle drive for a future driveaway process, the method comprising:
- receiving a time signal comprising at least one indicator chosen from the group consisting of a pedestrian light signal emitter, a streetcar light signal emitter, a bus light signal emitter, and a bicycle path light emitter;
using the time signal received to determine a future change time of a traffic light signal emitter from red light to green light based upon a correlation between the time signal and an anticipated delay for the future change time; and
automatically starting an internal combustion engine of the motor vehicle drive at a start time which comes before the future change time by a predetermined duration.

7. A method for preparing a start/stop system of a motor vehicle drive for a future driveaway process, the method including:
-
determining a future driveaway process of the motor vehicle drive by detecting an increase in torque or an increase in speed or a start of a drive of at least one preceding vehicle; and automatically starting an internal combustion engine of the motor vehicle drive at the time at which the future driveaway process is determined or delayed with respect thereto by a predetermined duration. - View Dependent Claims (8, 9, 10)

11. A system for operating a motor vehicle drive, the system comprising:
-
an internal combustion engine for driving the motor vehicle; and a controller configured to; receive a time signal comprising at least one indicator chosen from the group consisting of a pedestrian light signal emitter, a streetcar light signal emitter, a bus light signal emitter, and a bicycle path light emitter; use the time signal received to determine a future change time of a traffic light signal emitter from red light to green light based upon a correlation between the time signal and an anticipated delay for the future change time; and automatically start the internal combustion engine of the motor vehicle drive at a start time which comes before the future change time by a predetermined duration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
