Vehicle driving support apparatus

A braking / driving force control unit determines whether or not the driver has a intention of lane change on the basis of the detected road shape and the steering amount. The braking / driving force control unit detects an obstacle which is an obstacle present rearward and sideward of the vehicle. The braking / driving force control unit determines whether approach prevention control for preventing an the vehicle from approaching to the obstacle should start, when it is determined that the driver has the intention of lane change and the obstacle is detected, and performs the approach prevention control for supporting prevention of the vehicle from approaching to the obstacle when it is determined that the control should start. At this time, the braking / driving force control unit determines detection accuracy of the road shape ahead of the vehicle and suppresses the determination of the start of the control when the detection accuracy is low.

Control apparatus for vehicle

Lane keeping control is ended in accurate timing which does not give an uncomfortable feeling to a driver. In a vehicle 10 which is provided with a steering mechanism 200, an EPS actuator 300, and a VGRS actuator 500 and which can change a rudder angle regardless of a driver's steering input due to the cooperative control of the aforementioned mechanism and actuators, an ECU 100 performs LKA end control. In the control, in cases where a winker lever 16 is operated in a period of performing LKA control for making the vehicle 10 follow a target driving route, if the indicated direction of the winker lever 16 is different from a generation direction of generating an assist steering torque TA of the EPS actuator 300 in the LKA control, the LKA control is promptly ended. In cases where the indicated direction is equal to the generation direction, if a steering angle MAdrv corresponding to the driver's steering input exceeds a steering angle MAlka generated by the LKA control, the LKA control is ended.

Fuel-saving drive recommendation system and fuel-saving drive recommendation method

A fuel-saving drive recommendation system is mounted on a vehicle that includes a step-gear automatic transmission of which a gear is shifted in response to a gear instruction signal. The fuel-saving drive recommendation system calculates a required driving force based on an amount by which an output operating component is operated by a driver and a gear of the automatic transmission, makes determination for fuel-saving drive for the vehicle based on the required driving force and notifies the determination result. The fuel-saving drive recommendation system calculates a required driving force for performing output control on an engine and a required driving force for determining whether it is a fuel-saving drive state. A determination gear signal different from the gear instruction signal is used when the determination required driving force is calculated, and is changed to coincide with the gear instruction signal that has been changed.

Drive control apparatus for vehicle

A drive control apparatus for a vehicle includes: a control unit that controls drive force output from an engine in accordance with operation of an accelerator pedal; and a shift mechanism capable of selectively switching a shift position to a driving position or a non-driving position. The shift mechanism transmits the drive force to wheels when the shift position is in the driving position, and interrupts transmission of the drive force when the shift position is in the non-driving position. The control unit executes a drive force restriction process of reducing the drive force when the shift position is switched from the non-driving position to the driving position while the accelerator pedal is in an on state, and, when the switching is from a neutral position, the control unit changes a mode of reducing the drive force in accordance with a continuation time of the neutral position.

Voice signal decoding device and voice signal decoding method

A voice signal decoding device includes a first decoder, a second decoder, a signal switch, and a noise adder. The first decoder decodes first encoded data encoded by a first encoding method. The second decoder decodes second encoded data encoded by a second encoding method. The second encoded data has a narrower band than a band of the first encoded data. The signal switch switches an output signal of t first decoder and an output signal of the second decoder. The noise adder adds a noise signal to a high-frequency band in the output signal of t second decoder when the signal switch switches an output signal from the output signal of the first decoder to the output signal of the second decoder. The high-frequency band is a band where a signal component is lacking as compared with the output signal of the first decoder.
