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. If the answer is determined to be Yes, then information indicative of the contents of a desired restriction datum of the running performance can be read from a storing device storing a plurality of restriction data each used to restrict the running performance of the vehicle on the basis of information indicative of the running state detected by a running state detecting device, and of information indicative of the operating state detected by an operating state detecting device, thereby making it possible to restrict the running performance of the vehicle.

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.

摘要:
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. It is therefore possible to automatically determine to what degree the driving of the electrical loads should be restricted according to the degree of the residual capacity of the electric source.

An electric vehicle includes a device which determines, on the basis of the gradient of a road surface, a target acceleration of the vehicle in the case where the operational states of an accelerator (gas) pedal and a brake pedal of the vehicle are an OFF state when the vehicle is traveling on a down-slope road, a device which determines the correction amount of a regenerative torque for bringing the actual acceleration of the vehicle close to the target acceleration, a device which determines a basic target torque of an electric motor, which becomes a regenerative torque when the operational state of the accelerator (gas) pedal is the OFF state, on the basis of the operational state of the accelerator (gas) pedal, and a device which determines a target torque by correcting the basic target torque on the basis of at least the aforesaid correction amount. The output torque of the electric motor is controlled to the determined target torque. Thus, when the electric vehicle travels on the down-slope road, the regenerative operation of the electric motor is accomplished such that an acceleration suited to the gradient of the road surface can be generated in the vehicle while minimizing the influences of disturbance factors.
