Abstract: When a catalyst temperature is lower than a predetermined temperature on a second or subsequent start of an engine since system activation of a vehicle, a catalyst warm-up request is output for the purpose of warming up a catalyst in a catalytic converter. An output limit Wout of a battery is not increased in response to a second or subsequent output of the catalyst warm-up request, while being increased in response to a first output of the catalyst warm-up request. Accordingly, the catalyst warm-up in response to the second or subsequent output of the catalyst warm-up request since the system activation suppresses excessive output of electric power from the battery and thereby suppresses deterioration of the battery. Catalyst warm-up is performed in response to the second or subsequent output of the catalyst warm-up request. This suppresses deterioration of emission. As a result, this configuration satisfies both (balances) suppression of deterioration of the battery and suppression of deterioration of emission.

Abstract translation: 当催化剂温度低于预定温度时，由于车辆的系统启动，发动机的第二次或随后启动，为催化转化器中的催化剂预热而输出催化剂预热要求。 响应于催化剂预热请求的第二次或随后的输出，响应于催化剂预热请求的第一次输出而增加电池的输出限制Wout不会增加。 因此，由于系统启动后响应于催化剂预热请求的第二次或随后的输出的催化剂预热，抑制了来自电池的电力的过度输出，从而抑制了电池的劣化。 响应于催化剂预热请求的第二次或随后的输出进行催化剂预热。 这抑制了排放的恶化。 结果，这种结构既满足（平衡）抑制电池劣化和抑制发光劣化的作用。
