Patent number: 8977459Abstract: When a rear wheel total drive force is smaller than a rear wheel drive force difference and the rear wheel drive force difference cannot be realized by setting a left-right distribution of the rear wheel total drive force, an inside wheel target drive force is set unconditionally to a minimum initial drive force required to prevent a three-wheel drive state and an outside wheel target drive force is set to a value equal to the sum of the initial drive force and the rear wheel drive force difference, which is a value with which the rear wheel drive force difference can be realized while the inside wheel target drive force is set to the initial drive force. In this way, a drive force distribution control apparatus gives priority to realizing the rear wheel drive force difference and emphasizes achieving a target behavior over achieving a four-wheel drive performance.Type: GrantFiled: July 5, 2011Date of Patent: March 10, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Yuuki Ozawa

Patent number: 8874316Abstract: A current increase-decrease amount (?I?*) computed by a command current increase-decrease amount computing unit is added to an immediately preceding value (I?*(n?1)) of a command current value (I?*) in an adder. The command current value (I?*) obtained by the adder is given to a high/low limit limiter. The high/low limit limiter limits the command current value (I?*), obtained by the adder, to a value between a low limit value (?min (?min?0)) and a high limit value (?max (?max>?min)). A high limit value setting unit obtains the high limit value (?max) corresponding to the vehicle speed detected by the vehicle speed sensor, from a vehicle speed-vs.-high limit value map set by a map creating/updating unit, and sets the obtained high limit value (?max) in the high/low limit limiter.Type: GrantFiled: August 8, 2011Date of Patent: October 28, 2014Assignee: JTEKT CorporationInventors: Yuji Kariatsumari, Terutaka Tamaizumi, Isao Namikawa

Patent number: 8874315Abstract: When the estimated motor temperature becomes equal to or higher than the first predetermined temperature, an addition angle correction unit temporarily decreases the absolute value of the addition angle output from an addition angle limiter at time intervals. The addition angle correction unit makes the time interval shorter as the estimated motor temperature increases. When the time interval becomes equal to or shorter than the predetermined threshold, that is, when the estimated motor temperature becomes equal to or higher than the second predetermined temperature that is higher than the first predetermined temperature, the addition angle correction unit notifies a command current value changing unit of a current stop command. Thus, the ?-axis command current value is changed to 0, and therefore the steering mode is shifted to the manual steer mode.Type: GrantFiled: November 10, 2010Date of Patent: October 28, 2014Assignee: JTEKT CorporationInventors: Yuji Kariatsumari, Yoshihiro Itatsu, Yoshinobu Shimizu
