Patent ID: 6843337

Claim:
A control system in a hybrid vehicle including an engine and a motor as driving sources, the system comprising: a warm-up accelerating section for accelerating warm-up of the engine by controlling the ignition timing of the engine according to a temperature of water for cooling the engine; and a power generation control section for controlling electrical power generation by the motor according to a remaining charge of a battery of the vehicle, wherein the warm-up accelerating section has an ignition timing correcting section for correcting the ignition timing according to an amount of generated electrical power which is controlled by the power generation control section, and wherein when the remaining charge of the battery is greater than a predetermined upper limit, the ignition timing is retarded by the warm-up accelerating section without performing the electrical power generation using the motor; and when the remaining charge of the battery is equal to or less than the predetermined upper limit, if power consumption of the battery is equal to or less than a predetermined amount, electrical power is generated by the motor according to the control of the power generation control section and the ignition timing is retarded by the warm-up accelerating section, and if power consumption of the battery is larger than the predetermined amount, electrical power is generated by the motor according to the control of the power generation control section without retarding the ignition timing.
