Controller of vehicle
First Claim
1. A controller of a vehicle comprising an engine for outputting driving rotation by a crank shaft, a motor connected to the crank shaft of the engine, and a battery for supplying electric power to the motor, the controller of the vehicle comprising:
- engine stopping means for stopping the operation of the engine at a stopping time of the vehicle;
motor control means for driving the vehicle and rotating the engine by controlling the driving of the motor at a starting time of the vehicle;
load condition detecting means for detecting a load condition having an influence on the magnitude of load torque given to the motor during the stoppage of the engine when the vehicle is started by the motor;
ignition condition setting means for setting an ignition condition for starting the engine on the basis of the load condition detected by the load condition detecting means;
ignition condition judging means for judging that the ignition condition set by the ignition condition setting means is satisfied; and
engine ignition means for starting-up the engine on the basis of the judging result of the ignition condition judging means.

Abstract
A controller of a vehicle for igniting, i.e., starting-up an engine on the basis of a load condition. When a starting condition judging device judges that the vehicle is advanced, i.e., starts moving, during an idle stop, an engine water temperature detector and a lubricating oil temperature detector of a load condition detector detect, e.g., the water temperature of the engine and the temperature of lubricating oil of an automatic speed change gear as a load condition having an influence on the magnitude of the load torque given to a motor. When an ignition condition setting device sets an ignition condition for starting the engine on the basis of the load condition and an ignition condition judging device judges that the ignition condition occurs, an engine ignition device ignites the engine. Thus, when the load with respect to the motor is large, the engine is ignited from low speed rotation and electric power consumption is reduced. In contrast to this, when the load is small, the engine is ignited by high speed rotation and the consumption of fuel is reduced. Thus, fuel cost of the vehicle is improved.
