To provide an alarm system for a vehicle that can appropriately raise an alarm to a driver of a vehicle that is entering an intersection. An alarm systemfor a vehicle includes an alarm line setting partthat sets a right alarm lineand a left alarm lineboth extending forward from a vehicle. The alarm line setting partsets the length of the right alarm lineand the left alarm lineat L1 when the vehicle is running in a straight line. The alarm line setting partsets the length of the right alarm lineor the left alarm lineat a length different from L1 when the vehicleis to turn left or right at an intersectionto enter a first laneor a second lane

Alarm system for vehicle

To provide an alarm system for a vehicle that can reduce alarms that can irritate a driver. An alarm systemfor a vehicle includes an alarm line setting partthat sets a right alarm lineand a left alarm linein front of a vehicle, and an alarm unit control partthat activates a speakerand a displaywhen the velocity of the vehicleis equal to or less than a predetermined velocity and a collision determination partdetermines that an object will cross the right alarm lineor the left alarm linewithin a predetermined time. When the vehicleis decelerating, the alarm unit control partperforms an alarm reduction control that suppresses operation of the speakercompared with when the vehicleis not decelerating.

A vehicle obstacle detection device comprises: a radar unit provided between a back surface of a bumper and a wheel and configured to detect an obstacle by transmitting a radio wave through the bumper; and a misdetection prevention member for preventing misdetection in the radar unit by suppressing the occurrence of an own-vehicle's wheel reaching wave which is a part of a transmission wave and which passes between a transmitter section of the radar unit and the back surface of the bumper and reaches the wheel of the own vehicle.

Obstacle detection device for vehicle

A transmission structure for an automotive vehicle having a power unit includes an engine and a transmission device, including a power transmitting device connected to an output shaft of the engine, for transfer from an output of the engine to the transmission device. A first housing for the power transmitting device, a second housing for the transmission device, connected to the first housing, a differential device, housed in the first housing and positioned so as to be offset from an output shaft of the engine, and a reinforcement element, having one end portion connected to an upper surface of the first housing and another end portion connected to both side surfaces of the second housing, are provided.
