Patent number: 7784575Abstract: A hybrid vehicle drive control system is configured to perform engine startup when switching from an electric drive mode to a hybrid drive mode, without creating a sense of output torque loss. In particular, a controller selectively controls a first clutch disposed between the engine and the motor/generator and a second clutch disposed between the motor/generator and a drive wheel to switch between an electric drive mode in which the first clutch is released and the second clutch is engaged, and a hybrid drive mode in which both the first and second clutches are engaged.

Patent number: 7586290Abstract: A state of charge of a battery (1) that drives a motor (6) is computed based on a discharge current measured by a current sensor (3) when the discharge current of the battery (1) does not exceed a rated discharge range of the battery (1). When the discharge current of the battery (1) exceeds the rated discharge range, the state of charge of the battery (1) is computed by estimating the discharge current of the battery (1) from a motor control signal, whereby current changes over a wide range can be found with good precision using the sensor (3), which has a narrow but high resolution measurable range, and the state of charge can be accurately detected.Type: GrantFiled: June 10, 2005Date of Patent: September 8, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Takeshi Hirata, Tsuyoshi Yamanaka, Yuji Nakada
