摘要： PROBLEM TO BE SOLVED: To provide a controller of a hybrid vehicle in which an abnormal sound and impact are reduced when an engine 1 is started. SOLUTION: During giving an r.p.m. command to an MG 4, the regenerative control of the MG 4 is forbidden and the line pressure level or the pressure rise per unit time of a transmission 14 is limited. When the engine 1 is started by means of the MG 4, an abnormal sound due to a force acting reversely on a belt 3 connecting the engine 1 and the MG 4 or an impact of the vehicle due to the abrupt transmission of a driving force from the started engine to wheels can be prevented.

摘要： PROBLEM TO BE SOLVED: To solve the problems that noise is generated due to the distortion of a motor current waveform when a current control cycle and a carrier wave cycle differ from each other, and thereby a point that reflects a PWM command is varied; and that there may arise a possibility that the A-D conversion timing of each signal for use may be repeated when an effective cycle of current control is faster than a current command value operation. SOLUTION: Motor current detection is started at a prescribed phase and at a prescribed integral multiple frequency of power element switching. After the current detection, a switching command value is set at first timing for updating a power element command value, and a current of the motor is controlled by the newest current detected at the prescribed phase. Motor current control processing is started at a frequency of the prescribed integer multiplication of the switching during a period after the updating of the switching command value until the switching reaches its half cycle. The position of a motor magnetic pole is input during a period after the finish of the current control processing that starts the operation processing of a required drive force and before a prescribed time for starting the motor current detection, thus preventing repetition with the other analog signal input.

摘要翻译：要解决的问题：为了解决当电流控制周期和载波周期彼此不同时由于电动机电流波形的失真而产生噪声的问题，从而反映PWM指令的点是多变; 并且当电流控制的有效周期比当前指令值操作更快时，可能会出现可能重复使用的每个信号的A-D转换定时的可能性。
解决方案：电机电流检测在规定的相位和规定的功率元件切换的整数倍频率下开始。在电流检测之后，在用于更新功率元件指令值的第一定时设定开关指令值，并且通过在规定相位检测到的最新电流来控制电动机的电流。电动机电流控制处理以在切换指令值更新之后的时段内的切换的规定的整数倍的频率开始，直到切换达到其半周期为止。电动机磁极的位置在开始所需驱动力的操作处理的当前控制处理完成之后的时间段内，并且在用于启动电动机电流检测的规定时间之前被输入，从而防止与其他模拟信号重复输入。版权所有（C）2007，JPO＆INPIT
