Abstract
A hybrid vehicle including: an engine and a motor-generator for outputting drive forces to run a vehicle; and a brake pedal for applying a braking force to the running vehicle. While an engine braking force is being established, it is detected that the brake pedal is depressed. After this depression of the brake pedal, the vehicle speed is detected so that the regenerative braking is effected by the motor generator on the basis of the detected vehicle speed.
Claims16
A hybrid vehicle which has a plurality of prime movers individually controlled for running a vehicle, and a brake unit acting for running and stopping the vehicle, comprising:
- brake detecting means for detecting that the braking of the vehicle is executed by said brake unit, when the vehicle is run by one of said prime movers;
- vehicle speed detecting means for detecting the vehicle speed after the braking by said brake unit;
- decide means for deciding whether or not the actual vehicle behavior corresponds to that achieved by the braking, on the basis of the vehicle speed detected by said vehicle speed detecting means;
- and
- assist control means for controlling another of said prime movers so as to increase or decrease its output, when said decide means decides that the behavior of the vehicle does not correspond to the detected activation of the brake unit, to achieve a behavior of the vehicle consistent with activating said brake unit.
A hybrid vehicle which has a plurality of prime movers individually controlled for running a vehicle, and a transmission for setting a forward gear stage, a reverse gear stage and a neutral to transmit no drive force, comprising:
- action detecting means for detecting the gear stage or the neutral, which is set by said transmission;
- vehicle speed detecting means for detecting the vehicle speed;
- decide means for deciding whether or not the behavior of the vehicle corresponds to that set by said transmission, on the basis of the vehicle speed detected by said vehicle speed detecting means;
- and
- assist control means for controlling the output of any of said prime movers so that the vehicle may be kept in a stopped state.
A hybrid vehicle which has a plurality of prime movers individually controlled for running a vehicle, and a transmission for setting a forward gear stage, a reverse gear stage and a neutral to transmit no drive force, comprising:
- action detecting means for detecting the gear stage or the neutral, which is set by said transmission;
- acceleration detecting means for detecting an acceleration including the moving direction of the vehicle;
- decide means for deciding whether or not the behavior of the vehicle corresponds to that set by said transmission, on the basis of the acceleration detected by said acceleration detecting means;
- and
- assist control means for controlling the output of any of said prime movers so that the vehicle may be kept in a stopped state, when the acceleration fails to correspond to the state set by said transmission.
A hybrid vehicle which has a plurality of prime movers individually controlled for running a vehicle, and a transmission for setting forward gear stages and a reverse gear stage of which drive forces are different from each other, comprising:
- action detecting means for detecting that the gear stage in which the drive force to be established by wheels is raised, is set by the transmission;
- behavior detecting means for detecting that the action to increase the output of one of said prime movers is executed;
- decide means for deciding whether or not the action to increase the output of one said prime movers is over a preset reference value;
- and
- assist control means for executing the control of any of said prime movers so as to establish a braking force when the lowest one of the forward gear stages or the reverse gear stage is set by said transmission, when the vehicle speed is within a preset speed range and when no braking action is executed.
