Patent number: 5635903Abstract: Based on detected information from a start sensor, a rotational speed sensor (or a vehicle speed sensor), and an accelerator opening sensor, a simulated sound selector device controls a simulated sound source device to generate a simulated sound signal corresponding to an operating condition of an electric vehicle when it starts, runs and is accelerated or decelerated, and also controls a sound level switcher device to adjust the level of the simulated sound signal. The simulated sound signal which is generated by the simulated sound source device and adjusted in level by the sound level switcher device is amplified by amplifiers, which drive respective loudspeakers to produce simulated sounds. The sound level switcher device is also controlled based on an ambient noise level detected by a noise sensor.Type: GrantFiled: December 21, 1994Date of Patent: June 3, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Makoto Koike, Masashi Kitagawa, Kazunari Ishiguro

Patent number: 5426589Abstract: Disclosed herein is a method of and an apparatus for limiting electrical loads due to electrical equipment on an electric vehicle. In the electrical load limiting apparatus, a desired running distance is inputted by a desired running distance inputting device and a depth of discharge of a battery is detected by a battery condition detecting device. Ambient environment data for the electric vehicle are obtained from an illuminance sensor, a temperature sensor and a raindrop sensor.

Patent number: 5416702Abstract: A vehicle electrical-load limiting apparatus wherein the priority given over a plurality of electrical loads, for restricting the driving of the electrical loads mounted on a vehicle, is first decided in order of importance and the amount of drive restriction of each of the electrical loads is then determined based on the remaining capacity of a vehicle electric source, thereby restricting the driving of the electrical loads. A fuzzy inference is carried out by making use of membership functions corresponding to both (a) the deviation indicative of the difference between a standard value set for each electrical load attached to the vehicle and a value of an electrical load when now in use, and (b) the residual capacity of the electric source. Then, the amount of the drive restriction of each of the electrical loads is obtained from the result of the fuzzy inference.Type: GrantFiled: May 15, 1992Date of Patent: May 16, 1995Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Kitagawa, Kenichiro Kimura

Patent number: 5367455Abstract: A running performance control apparatus suitable for use in an electric vehicle, which is capable of restricting the running performance of the vehicle when the capacity of a battery of the vehicle is reduced to the preset residual capacity. The battery capacity reduced to the preset residual capacity is detected and a vehicle running state including the speed of a running vehicle and the acceleration of the vehicle, is detected. An operating state, including shift positions of a transmission of the vehicle and the degree of opening of a vehicle accelerator is detected. When the battery capacity is reduced to the preset residual capacity, it is determined whether the vehicle running state should be restricted.Type: GrantFiled: July 31, 1992Date of Patent: November 22, 1994Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Kitagawa, Kenichiro Kimura, Takahiro Iwata

Patent number: 5125483Abstract: An electric brake system for a motor vehicle has a plurality of braking force generating mechanisms associated with respective road wheels and including electronic actuators mechanically separate from a brake pedal. In the event of a failure of at least one of the braking force generating mechanisms, the electric brake system selects and operates normal braking force generating mechanism or mechanisms for braking the motor vehicle stably with boosted braking forces. The braking force generating mechanisms are mechanically separate from the brake pedal and operable independently of each other. Failure detecting circuits are associated respectively with the braking force generating mechanisms, for detecting a failure of the braking force generating mechanisms and producing a failure signal representing the failure. The electric brake system includes a controller for controlling the braking force generating mechanisms in response to the signal from the brake pedal.Type: GrantFiled: November 12, 1991Date of Patent: June 30, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masashi Kitagawa, Yasuhiko Fujita, Toshiaki Arai

Patent number: 5058918Abstract: A suspension system for use on a motor vehicle includes a suspension having a leaf spring as a resilient member, and a plurality of strain gauges mounted on the leaf spring in suitable locations thereon. The value of a strain of the leaf spring in a particular position where one of the strain gauges is disposed is estimated on the basis of the measured value of a strain which is detected by another strain gauge. The difference between the estimated strain value and the value of a strain detected by the strain gauge in the particular position is then calculated. A deteriorated condition of the leaf spring can now be determined according to the calculated difference which is checked according to a preset reference or criterion.Type: GrantFiled: March 7, 1990Date of Patent: October 22, 1991Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsunori Nakaya, Masashi Kitagawa
