Patent number: 8096919Abstract: When a torque control value (TR) is larger than a threshold value and vehicular speed (SV) is lower than a threshold value an upper temperature limit setting unit sets the upper temperature limit of a motor generator at an upper temperature limit (TS2) higher than a normally set upper temperature limit (TS1). A torque limitation control controls limiting a torque of the motor generator, as based on a motor temperature (T) and the upper temperature limit set by the upper temperature limit setting unit.Type: GrantFiled: December 28, 2006Date of Patent: January 17, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keiji Takizawa, Hiroshi Aihara

Patent number: 8089234Abstract: When a motor temperature exceeds a threshold value, a torque control unit reduces a torque control value for a motor generator. A torque limitation control unit determines from torque control value and vehicular speed whether limiting a torque by the torque control unit should be alleviated, and if so the torque limitation control unit activates a signal for a predetermined period of time. When the signal is activated, the torque control unit stops reducing the torque control value and fixes the torque control value to be constant.Type: GrantFiled: April 3, 2007Date of Patent: January 3, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keiji Takizawa, Hiroshi Aihara
