Patent number: 5608308Abstract: The opening of the intake air control valve of an engine which actuates a generator on a hybrid vehicle is basically controlled by an intake air control valve control assembly to cause the engine to produce a power output corresponding to a target generated output which is determined by a target generated output setting assembly based on an operating condition of the hybrid vehicle. When regenerative braking of a propulsive electric motor is detected by a regenerative braking detector, the opening of the intake air control valve is corrected in a direction to decrease. Even when the load on the engine drops sharply or is greatly reduced by regenerative braking of the propulsive electric motor, the engine is prevented from racing, and from discharging unwanted exhaust emissions and also from suffering undue vibrations.Type: GrantFiled: August 9, 1995Date of Patent: March 4, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takeo Kiuchi, Shigeru Ibaraki

Patent number: 5469816Abstract: A control mechanism for an electric generator motor which can prevent excessive charging and insufficient capacity of an electrical power storage device includes a controller controlling operation of the electric generator motor when a total of restorable electrical power calculated on the basis of vehicle state and a present capacity of the electrical storage device is smaller than a specified reference capacity. The control mechanism effects a motor operation, i.e., application of torque, of the generator motor within a range in which the capacity of the electrical storage device does not fall below a specified minimum charge level required for driving vehicle auxiliary devices. The control mechanism effects motor operation of the electric generator motor with continuously changing restorable electrical power which has a positive correlation with an effective amount of depression of a brake pedal.Type: GrantFiled: September 1, 1994Date of Patent: November 28, 1995Assignee: Nippondenso Co., Ltd.Inventors: Takaji Murakawa, Toyoji Yagi, Hiroshi Tashiro

Patent number: 5359228Abstract: An operating method for a hybrid car which has an electric motor for driving the vehicle and an internal combustion engine for power generation. Using an operational expression including a motor output correction factor whose value is variably adjusted to different values depending on whether the engine is operated for battery charging or the engine is stopped, a required motor current supply that matches the vehicle operating state represented by an actual vehicle speed and an accelerator pedal depression depth is calculated, and the motor current supply is controlled in accordance with the result of the calculation. Consequently, the cruising range of the hybrid car is increased, and also the power performances and exhaust gas characteristics of the hybrid car are improved.Type: GrantFiled: May 14, 1993Date of Patent: October 25, 1994Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventor: Masato Yoshida

Patent number: 5327992Abstract: A method for controlling a hybrid drive consisting of an internal combustion engine and at least one electric motor which can be driven via an electrical energy source, in which the electric motor can be operated as a generator when required. In order to reduce the fuel consumption and the emission of noxious substances of the internal combustion engine in those operating ranges in which the torque to be output by the internal combustion engine to overcome the instantaneous tractive resistances lies below a torque corresponding to ideal operation of the internal combustion engine with respect to efficiency and/or exhaust gas behavior, the internal combustion engine is operated essentially with the torque corresponding to ideal operation. The differential torque between the torque corresponding to ideal operation and the torque to be output by the internal combustion engine to overcome the instantaneous tractive resistances is used to drive the electric motor which is switched as a generator.Type: GrantFiled: April 28, 1993Date of Patent: July 12, 1994Assignee: Mercedes-Benz AGInventor: Wolf Boll

Patent number: 5293076Abstract: A control apparatus for a vehicle equipped with an engine senses a condition indicating the capacity of the battery of the vehicle. When the capacity is below a prescribed level, the drive current to an actuator of the vehicle is adjusted to prevent the battery from becoming excessively discharged. In one form of the invention, the drive current is decreased to decrease the load on the battery. In another form of the invention, the actuator is controlled to increase the engine speed, thereby increasing the output of a generator driven by the engine. In another form of the invention, the actuator is controlled to stop the engine. When the engine is restarted, the initial rotational speed of the engine is high enough for the generator to recharge the battery.Type: GrantFiled: April 14, 1992Date of Patent: March 8, 1994Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Wataru Fukui
