Patent number: 6281663Abstract: A reduction in charging time is achieved while suppressing any deterioration in the lifetime of the battery. A battery temperature increase margin is determined from the battery temperature at charge commencement and the upper limit value of the battery temperature. Moreover, the target charging capacity is determined from the initial state of charge at charge commencement and the target state of charge at charge completion. Furthermore, a value of an upper limit of the battery temperature increase is determined from these. Then, the battery charge current maximum value is set by map referral based on the value of an upper limit of the battery temperature increase such that the temperature of the battery during charging does not exceed the upper limit value. A driver performs the battery charging using a charge current value that has been set on the basis of the battery charge maximum value.Type: GrantFiled: November 13, 2000Date of Patent: August 28, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kazuhiko Yagi, Takashi Ishikura, Takeshi Sakurai

Patent number: 5577816Abstract: The ABS is provided with a modulator, and when the ABS is activated, control of the caliper pressure by the driver, is modified by the operation of the modulator having the aforementioned inlet valve (normally closed to a pressurized fluid source) and aforementioned outlet valve (normally open to a fluid exit), both controlled by the above-described control logic circuit. The modulator increases or decreases the caliper pressure, in response to changes in the pressurized fluid, regulated by such valves. Depending on the operation of the control logic circuit described above, three events may occur. When the inlet and outlet valves are not operated (i.e. their normal state), the modulator releases pressurized fluid through the output valve, and increases caliper pressure, to increase braking up to a predetermined maximum. If only the outlet valve is operated (i.e. both the inlet and outlet valves are closed), the modulator remains in a constant state and likewise, the caliper pressure is kept constant.Type: GrantFiled: July 28, 1994Date of Patent: November 26, 1996Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Osamu Suzuki, Keishin Tanaka, Tatsuo Hayashi, Takushi Matsuto, Chiaki Kumagai, Takeshi Sakurai, Atsuo Ota

Patent number: 5573313Abstract: A method and apparatus for controlling brakes using a reciprocating cut valve actuated by an expander piston that is moved via a crank pin on a crank shaft. The cut valve cuts off caliper pressure and adjusts the volume and pressure of an output hydraulic chamber to effectuate antilock braking. When changing from antilock braking to normal braking, the movement of the expander piston is controlled by repeatedly changing a crank angle of the crank pin during specified time intervals. The rate of increase in caliper pressure can be set according to (1) detected brake operation which is detected from a present crank angle and a target crank angle and (2) the frictional state of the road surface which is estimated from vehicle acceleration/deceleration.Type: GrantFiled: May 22, 1995Date of Patent: November 12, 1996Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Osamu Suzuki, Keishin Tanaka, Tatsuo Hayashi, Takushi Matsuto, Chiaki Kumagai, Takeshi Sakurai, Atsuo Ota
