Driving support ECU sets a driver's state to “temporarily abnormal” and decelerates a vehicle when a driver of the vehicle has been first determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Driving support ECU changes the driver's state to “regularly abnormal” in a case when the abnormal state of the driver remains unchanged when a vehicle speed decreases to a set vehicle speed, and at this point, reports to a help net center HNC. With this configuration, a report to the help net center HNC can be made at an appropriate timing.

A recreational vehicle braking system having a tether system, a controller system, and a brake. The controller system activates a slowdown timer upon removal of the tether system from the vehicle and then activates a stop timer upon expiration of the slowdown timer.

A wheel chair with several new and useful features is provided. Those new and useful features provide the wheel chair with enhanced lateral stability, automatic cocking of an automatic locking device whenever an occupant sits in the wheel chair, and a holding mechanism that enables the wheel chair to be freely wheeled about when there is no occupant, and automatically move to a cocked state as soon as an occupant sits on the chair. The result is an automatic locking system for a manual wheelchair that unlocks the wheels for intentional motion when the chair is occupied, and locks the wheelchair wheels immediately when it is unoccupied, yet in no way interferes with the typical locking mechanism of the standard manual wheelchair when so desired.

The intent to exit a vehicle when a driver attempts to exit a vehicle is detected by an exit intent detection unit, and regardless of whether or not the shift range other than the parking range is detected by a shift range detection unit, a securing control unit controls a vehicle securing unit and secures the vehicle when an intent to secure is detected by a securing intent detection unit. Thus, unintended vehicle movement after exiting is suppressed by securing the vehicle in a stopped state during exiting.

An emergency controller includes an emergency stop switch to be activated upon detection of an emergency, a control section to be enabled upon activation of the emergency stop switch, and an emergency stop mechanism configured to execute and release braking by a brake mechanism under control of the control section. The control section is configured to perform execution control for causing the emergency stop mechanism to execute braking by the brake mechanism and for stopping operation of the engine upon the condition that the emergency stop switch is activated while the engine is in operation. The control section is configured to perform restoration control for causing the emergency stop mechanism to release the braking by the brake mechanism upon the condition that the emergency stop switch is deactivated and the engine is started.

A motor initialization method for an electric booster brake system may include: determining, by a control unit, whether a key on signal of a vehicle is inputted; turning on a warning light and determining a battery voltage state of the vehicle, when the key on signal is inputted; and performing a motor initialization mode according to the determined battery voltage state.
