A system and a method of improving a braking performance during a failure of a brake-by-wire (BBW) device, includes BBW devices including electro-mechanical brakes provided for respective wheels of a vehicle and independently performing braking, and the BBW devices including controllers electrically connected to the electro-mechanical brakes, and the system includes a steer-by-wire controller configured for controlling front wheels through an electronic signal and a rear wheel steering (RWS) controller configured for controlling steering of rear wheels such that a rear wheel steering angle is to be controlled in the same or an antiphase of a front wheel steering angle, wherein when one of the controllers fails, at least one of the steer-by-wire controller and the RWS controller is configured to control steering based on whether a driver's required braking force exceeds a maximum braking force which may be generated by any one of the front and rear wheels.

A controller for a hybrid vehicle performs charging control when a shift range of the hybrid vehicle is a first range, and does not perform the charging control when the shift range of the hybrid vehicle is a second range, the charging control being control of charging a power storage device with electric power generated by a generator driven by an engine. The controller records diagnosis information when an SOC of the power storage device is equal to or lower than a first threshold value and the shift range of the hybrid vehicle is the first range, and does not record the diagnosis information when the SOC of the power storage device is equal to or lower than the first threshold value and the shift range of the hybrid vehicle is the second range.

A driver assistance system of a vehicle includes a forward viewing camera, a forward sensing non-vision sensor, and an ECU having at least one data processor. The ECU, responsive to processing of image data captured by the camera and to processing of sensor data captured by the non-vision sensor, provides a driving assistance function for the vehicle. The ECU detects presence of objects forward of the vehicle via processing of captured image data and captured sensor data. The ECU determines an error in object detection by determining difference between object detection based on processing of captured image data and object detection based on processing of captured sensor data. The ECU disables at least part of the driving assist function at least in part responsive to the determined error in object detection being greater than a threshold error level.

A hybrid vehicle includes: an engine; a battery; a power converter; a relay; a first controller; and a second controller. The second controller is configured to control the engine and the power converter according to allowable charging power and allowable discharging power received from the first controller. The second controller has, as control modes, a normal mode in which the relay is closed and the battery and the power converter are electrically connected and a batteryless drive mode in which the relay is opened to cause the hybrid vehicle to move with the battery electrically disconnected from the power converter. The second controller is configured to select the batteryless drive mode when at least one of the magnitude of the allowable charging power and the magnitude of the allowable discharging power become smaller than a first predetermined value.

A vehicle may have actuators, including a drive device with a drive motor that can act on a drive wheel, a brake device with a brake that can act on a drive wheel, and/or a steering device with a steering sensor by way of which the steering angle of a wheel is adjustable, a vehicle movement controller, and a setpoint value input means, a setpoint value processing means for detecting setpoint value settings of the setpoint value input means, to calculate a yaw acceleration setpoint value and translational acceleration setpoint values from the setpoint value settings. The setpoint value processing means may be configured to transfer the calculated yaw acceleration setpoint value and translational acceleration setpoint values to the vehicle movement controller, which is configured to actuate one or more of the actuators such that the yaw acceleration setpoint value and the translational acceleration setpoint values are reached.

A safety system for a baggage tractor is provided that addresses the problems associated with tipping over or flipping of vehicles due to excessive speed around turns. Additionally, the safety system for a baggage tractor is provided that is fully integrated to ease replacement of a combustion engine in a baggage tractors with an electric motor and automated safety control system.

A method for reactivation of an electrical system of a vehicle comprising a first electrical system operating at a first lower voltage and a second electrical system operating at a second higher voltage, comprising: detecting a fault or a crash situation in the second electrical system; disconnecting a power source of the second electrical system; determining the fault of the second electrical system is no longer present or that the crash situation is resolved; reconnecting the power source to the second electrical system and increasing the voltage of the second electrical system from zero to an intermediate voltage lower than the second voltage; and if a detected current in the second electrical system is higher than a current threshold value; or if a detected voltage of the first electrical system is higher than a voltage threshold value; reducing the voltage of the second electrical system to zero.

An abnormality detection apparatus for a mobility entity and for detecting an abnormality in a network system is provided. The network system includes a first network and a second network that use different communication protocols. A first communication circuit receives state information indicating a state of the mobility entity. The state information is acquired from the second network. A second communication circuit transmits and receives a first frame according to a communication protocol used in the first network. A memory stores an abnormality detection rule. A processor detects, based on the state information and the abnormality detection rule, whether a control command included in the first frame received by the second communication circuit is abnormal. In a case where the control command is abnormal, the processor prohibits the control command from being transmitted.

A vehicle driving assist apparatus has surrounding sensors which detect vehicle surrounding situations and driving assist systems which assist a driving operation of a driver, based on the vehicle surrounding situations. The vehicle driving assist apparatus determine whether the surrounding sensors malfunction. When the at least one electronic control unit determines that at least one of the surrounding sensors malfunctions, the vehicle driving assist apparatus determine operable driving assist systems and inoperable driving assist systems, and causes a display device to display both of a display indicating that at least one of the surrounding sensors malfunctions and a display indicating a list of the operable driving assist systems and the inoperable driving assist systems in a manner that the driver can realize which driving assist systems are operable and which driving assist systems are inoperable.

Methods and systems are provided for driveline control and diagnostics. In one example, a vehicle system may include a controller with instructions stored in a first memory unit and when executed by a first processing unit cause the controller to write mechanical vehicle component operating data to a shared memory unit. The controller further includes instructions stored in a second memory unit that when executed by a second processing unit cause the controller to read the mechanical vehicle component operating data to determine data validity.
