摘要:
When the remaining capacity of a battery on a hybrid vehicle is smaller than a threshold value or the battery is unable to output the amount of electric energy required to propel the hybrid vehicle with a propulsive electric motor, the engine is started by a generator which operates in a motor mode. After the engine has been warmed up, the generator operates in a generator mode to generate electric energy which is supplied to the battery and the propulsive electric motor. The threshold value for the remaining capacity of the battery is greater as the atmospheric pressure is lower. Therefore, if the hybrid vehicle is running under a low atmospheric pressure such as on a highland, the electric energy is supplied from the generator to the battery and the propulsive electric motor at an early stage where the capacity of the battery is relatively high. The generator also starts to generate electric energy when the battery is unable to output an amount of electric energy sufficient enough to propel the hybrid vehicle.

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.
