Driving assistance control apparatus for vehicle
ActiveUS20170088174A1Reduce steering angle deviationSolve the large energy consumptionBrake system interactionsSteering linkagesSteering angleEngineering
An apparatus includes a steering assist torque determination unit and a steering assist torque control unit. The steering assist torque determination unit determines a steering assist torque including a first component that is determined on the basis of a deviation between an actual steering angle and a target steering angle for achieving a target path determined irrespective of driver's steering. The steering assist torque control unit controls a steering assist mechanism such that the steering assist torque is applied. The ratio of the magnitude of the first component of the steering assist torque to the deviation between the target steering angle and the actual steering angle is determined on the basis of the magnitude of the deviation between the steering assist torque and the driver's steering torque in a past predetermined period.

Current drive circuit for light emitting diode
ActiveUS8492982B2Simple wayEasy to operateElectrical apparatusStatic indicating devicesBurst dimmingPhase shifted
A pulse width modulated dimming pulse signal PWM is input to a control input terminal P5. A standby terminal P6 receives a standby signal STB that indicates switching between a standby state and an operating state of a current drive circuit 8. A burst dimming terminal BS is provided to each of eight respective channels. Each burst dimming terminal BS receives a voltage at one terminal (cathode) of a corresponding LED string 6. When the voltage level of the standby signal STB is included in a first voltage range, a burst controller 9 is set to an all channel common mode, and when it is included in a second voltage range, the mode is set to a phase shift mode φSHIFT. The burst controller 9 set to the phase shift mode φSHIFT automatically sets the phase shift angle according to the number of connected LED strings 6.
