This ground short failure detection device can improve the accuracy of determining a ground short failure. The ground short failure detection device changes the potential of each of two signal lines, and transmits or receives data between a plurality of node devices. The ground short failure detection device comprises: a current measurement unit that measures a current value of a current flowing through each of the two signal lines; a determination unit that determines whether a difference between the measured current values exceeds a predetermined value, and when the difference exceeds the predetermined value, outputs a result indicating that a ground short failure occurs in a low-potential side signal line that has a relatively low potential in a dominant level among the two signal lines; and a control unit that controls the determination unit to determine whether the difference exceeds the predetermined value when a predetermined signal is completely transmitted.

Ground short failure detection device and node device

A coasting control device capable of avoiding coasting control during running on road having a small coefficient of friction between a tire and a road surface ('low &#x3bc; roads') includes a low &#x3bc; road running recognition unit which recognizes that a vehicle is running on a low &#x3bc; road and a unit for prohibiting coasting control during low &#x3bc; road running when the low &#x3bc; road running recognition unit recognizes that the vehicle is running on a low &#x3bc; road.

Coasting control device

A coasting control device for avoiding dangerous modes such as tire lock up upon the end of coasting control. The device, which performs coasting control to disengage the clutch and to reduce the engine revolutions per minute (RPM), also prevents a gearshift operation during coasting control.

A coasting control device capable of avoiding coasting control during turning is provided. A turning recognition unit that recognizes that a vehicle is turning and a unit for prohibiting coasting control during turning that prohibits coasting control when the turning recognition unit recognizes that the vehicle is turning are provided.

A coasting control device that prevents failures due to deterioration of a release bearing. The device includes an cumulative disengagement time measuring unit cumulatively measuring a duration of time that a clutch is being disengaged during coasting control, and an overtime restricting unit prohibiting coasting control when the measured cumulative clutch disengagement time has exceeded a predetermined time giving an indication of fatigue of a member of the clutch, and/or an overtime alarm unit providing an alarm when the measured cumulative clutch disengagement time has exceeded a predetermined time giving an indication of fatigue of the member of the clutch.

A coasting control device for reducing uneasiness experienced by a driver when pressing a clutch pedal during coasting control. The device includes a clutch control unit that, when the clutch pedal is pressed during coasting control, controls an actuator to cause an amount of hydraulic oil that depends on the amount of depression of the clutch pedal to be ejected from a clutch-free operating cylinder.
