Title: Starting device for vehicle
Inventor: OSADA MASAHIKO
IPC: F02N15/00
Filed: 2000-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten a starting time of an engine in an economical running system which stops the engine when a car stops and starts the engine when the car starts to move, and effectively compensate power consumed by a starter. SOLUTION: A vehicle mounts an existing low voltage power supply 1, and a high voltage power supply 2 having excellent charging efficiency. When the engine is started by connecting a key switch 7 with a starter terminal 7a, a voltage of the low voltage power supply 1 is applied to a starter motor 4. When the engine which stops while the car is stopping is started, a switch 6 is changed over and a voltage of the high voltage power supply 2 is applied to the starter motor 4. When the engine starts from a state of idle stop, the starter motor 4 rotates at a high speed by the high voltage power supply 2 so that the engine starts in a short period of time. Although a starter operation rate from the state of the idle stop becomes high, energy loss is suppressed and fuel economy can be improved because power of the high voltage power supply 2 with good charging efficiency is consumed to operate the starter motor 4.
