20090005947 | Slip Detection Apparatus and Slip Detection Method - The procedure of slip detection computes a right wheel speed Vr from a rotation speed Nm2 of a motor MG | 01-01-2009 |
20110227435 | MOTOR LOCK APPARATUS AND DRIVE APPARATUS FOR VEHICLE - A motor lock apparatus which can lock a rotor by a relatively simple structure and is advantageous to downsizing. The motor lock apparatus is applied to a motor generator having a stator and rotor which are installed so as to be rotatable relative to each other about a common axis, where the rotor has circumferentially arranged salient rotor poles projecting toward the stator. The motor lock apparatus has a lock plate and an actuator. The lock plate is fixed so as not to be rotatable about the axis and is movable between a locked position at which the lock plate is inserted between the salient rotor poles of the rotor and an unlock position at which the lock plate removed from between the salient rotor poles. The actuator drives the lock plate between the locked position and the unlocked position. | 09-22-2011 |

20150367833 | TRAVEL CONTROL DEVICE OF HYBRID VEHICLE - A travel control device is applied to a hybrid vehicle which includes a planetary gear mechanism capable of distributing power of an internal combustion engine to a first MG and an output part, and a second MG capable of outputting power to the output part. The travel control device allows the vehicle to travel in an acceleration-deceleration travel mode in which, when a high-speed steady travel condition is established during travel of the vehicle, acceleration travel for accelerating the vehicle with power output from the internal combustion engine and coasting travel for allowing the vehicle to coast with the internal combustion engine in a stop state are alternately repeated within a target vehicle speed range. In the travel control device, given power is output from the internal combustion engine at the time of acceleration travel, and the internal combustion engine is controlled such that the vehicle is accelerated at an acceleration such that the rotation speed of the first MG becomes zero. | 12-24-2015 |
