Abstract: The present invention intends to provide a control device for a fuel cell vehicle which suppresses the deterioration of driveability upon acceleration without increasing the size of a driving electric motor or a motor driver. When a requested output (PD_CAL) exceeds a first output limit determined depending on a continuous output rating of an electric motor 10 or a motor driver 5 and an increasing rate of the requested output (PD_CAL) exceeds a reference increasing rate, an upper-limit target output determining unit 52 determines an assist time used as a time during which the electric motor 10 can be operated continuously by the requested output (PD_CAL) on the basis of the requested output (PD_CAL) and an open-circuit voltage (Vbat_o) of a battery 3. Until the assist time is elapsed, the upper-limit target output (PD_LMT) is set to a second output limit (>the first output limit) determined depending on a short-time output rating of the electric motor 10 or the motor driver 5.

Abstract: An on-vehicle electronic control device improves safety so as to prevent an unnecessary start by means of an arousal timer circuit section. An on-vehicle electronic control device includes a main control circuit section and an arousal timer circuit section. A switching element is held in a closed-circuit operation with an output permitting signal that a watchdog timer circuit generates when a pulse cycle of a watchdog clear signal that a main CPU generates is normal, and thereafter an arousal output is reset in response to a forced OFF command from the main CPU. In the event that an arousal output is not reset, the arousal timer circuit section self-resets an arousal output after a predetermined time period has passed.

Abstract: A method for detecting decrease in tire air-pressure on the basis of wheel rotational information obtained from tires attached to a four-wheeled vehicle. The method includes the steps of: obtaining wheel rotational information obtainable from the respective tires, storing the wheel rotational information, and judging decrease in air-pressure of a tire. The step of judging decrease in air-pressure includes the step of adjusting a sensitivity of judgment upon multiplying a specified sensitivity coefficient to the wheel rotational information of the respective wheels of a front axis or those of the respective wheels of a rear axis of the vehicle and of judging a running condition of the vehicle. When it is determined that the vehicle is performing straight-ahead running, the judgment of decrease in tire air-pressure is performed only on the basis of wheel rotational information when performing straight-ahead running.

Abstract: Method and arrangement for automated control of a drive train (10) of a land vehicle to be executed when ground conditions exist that impede the initiation or continuation of travel of the vehicle such as being stuck on loose or slippery ground. The automated routine induces a rocking action in the vehicle purposed to aid in freeing the vehicle and permitting desired travel out of the area. As an initial step of the routine, it is determined whether such a ground condition exists. If so, drive power is applied, via a drive train (10) of the vehicle until the drive wheel (26, 30) bogs down or productive and continuous travel is established in the vehicle. A rocking-back action is permitted by a discontinuation of the drive power to the drive wheel (26, 30) of the land vehicle until a predetermined power resumption condition occurs. Reverse power can be optionally applied at this time. Otherwise, drive power is reapplied to the drive wheel (26, 30) for another attempt at forward progress.

The battery control unit performs the control of the push-walk traveling when the battery control unit receives the instruction of the push-walk switch via a rider and a vehicle state satisfies a preset condition.

Abstract: In a vehicle steering apparatus, front wheels are controlled to be turned by a computer program processing. A displacement/torque conversion section 51 converts a steering angle ? into a steering torque Td that is in relation of exponential function. A torque/lateral-acceleration conversion section 52 converts into an anticipated lateral acceleration Gd based upon the steering torque Td. A turning angle conversion section 55 calculates target turning angles ?d. A turning angle correcting section 61 obtains a slip angle ? of a slip generated on a vehicle. Then, the turning angle correcting section 61 corrects the target turning angle ?d based upon the obtained slip angle ?, thereby calculating a corrected target turning angle ?da. A drive control section 63 controls the steered wheels to be turned into the corrected target turning angle ?da. According to this, a driver can correctly perceive the generated anticipated lateral acceleration Gd, whereby he/she can easily drive the vehicle.

Abstract: A vehicle control device having a tire air pressure detecting unit for detecting tire air pressure of a vehicle having an engine mounted in the vehicle and outputting a tire air pressure signal, a tire air pressure reduction judging unit for judging on the basis of the tire air pressure signal whether the tire air pressure is reduced to predetermined pressure or less, and an output varying unit for varying driving force of the engine to tires according to a predetermined varying function on the basis of the judgment result. Even if a driver does not perceive an alarm when reduction of tire air pressure is detected, a driving system such as an engine, a transmission and a clutch is controlled according to a predetermined varying function. Therefore, for example, the rotational speed of the engine is periodically varied, and thus the driver has an uncomfortable feeling. Therefore, the driver can surely recognize the reduction of the tire pressure.

Abstract: In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the “cancel” state, the transition to the “in-control, inter-vehicle distance control” sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the “in-control, collision alarm” sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the “in-control, collision avoiding control” sub-state, and a collision avoiding control is performed.
