Disclosed is a portable electronic device comprising: a sensor; and a control unit controlling the sensor so as to obtain movement information of the portable electronic device in order to detect a movement of at least a part of a user's arm, determining whether the user is in a driving state on the basis of the movement information, automatically switching into a driving mode on the basis of the determination, and activating at least one function relating to driving among the functions of the portable electronic device on the basis of the switching into the driving mode.

A method for correcting a state of charge of a state of charge display of a traction battery of an electrically driven vehicle. The method includes detecting an attentiveness parameter of a driver of the vehicle with respect to the state of charge display, and step correction of the state of charge displayed on the state of charge display if the attentiveness parameter undershoots an attentiveness threshold value.

A method for identifying a driver change in a motor vehicle with the aid of an interior camera for monitoring the driver, which is characterized in that a driver change is detected when the head of the driver is not detected in the viewing range of the camera. In addition, a corresponding device and a computer program and a machine-readable memory medium are provided.

A drunk driving prevention system for a vehicle includes an eye symptom detector adapted for supporting in the vehicle at a position to detect eye symptoms of a driver, a control module operatively linked to the eye symptom detector for determining and analyzing whether the eye symptoms of the driver match with alcohol influenced eye symptoms, and a signal module operatively linked control module for generating a drunk driving signal in response to the alcohol influenced eye symptoms that suspect an alcohol concentration of the driver is above a predetermined threshold.

A situation awareness method can be used to provide information to a vehicle operator via first, second, and third substantially transparent ambient displays that are coupled to a windshield of a vehicle. The situation awareness method includes the following steps: (a) monitoring a physiological state of the vehicle operator; (b) monitoring a vehicle operating parameter of the vehicle; (c) monitoring a vehicle context data; (d) identifying a predetermined physiological condition based on the monitored physiological state of the vehicle operator; (e) identifying a predetermined vehicle operating condition based on the monitored vehicle operating parameter; (f) identifying a predetermined vehicle context condition based on the monitored vehicle context data; (g) adjusting a luminance of the first, second, and third substantially transparent ambient displays based on the identified predetermined physiological condition, the identified predetermined vehicle operating condition; and the identified predetermined vehicle context condition, respectively.

This design includes a steering wheel and app working together to operate properly. It uses interruption feature in wheel preventing texting, facetime, social sites, and social media up to two feet away from steering wheel. It will disarm feature when vehicle is placed in park. Inside steering wheel is an alcohol level detector and heart rate sensor. If over legal limit design will broadcast event in app. This causes steering wheel to lock. Design will then call and text contacts in app on behalf of driver. A gel pressure sensor under leather cover of steering wheel will detect pressure. If there is not enough pressure on steering wheel to safely operate it. Design alerts driver sending sound through speakers in steering wheel and flashes lights located on steering wheel. Design then calls and text contacts in app. Erratic speeds will cause design to call and text contacts in app.

The present disclosure provides a method for measuring clutch durability of an all wheel drive vehicle. The method includes: a damage degree securing step of accumulating and acquiring a damage degree of a clutch based on a clutch slip amount and clutch transfer torque when the clutch slips by a difference in rotary speed between a front wheel and a rear wheel; and a durability predicting step of predicting current durability of the clutch based on the difference between the accumulated and acquired damage degree and a reference damage degree of the corresponding clutch, an input shaft RPM of rotating the clutch, and a reference durability RPM of the clutch.

The present invention discloses a driving safety management system based on driver emotion and fatigue analysis. The system performs emotion recognition and/or sensor monitoring data analysis, and performs operations such as automatic speed limitation, speed control and braking to control vehicle actions. The system monitors a driver emotion and a fatigue status in real time during driving, and controls a vehicle driving status and/or issues a safety warning to a driver according to a monitoring result, so as to ensure the traffic safety of various vehicles from the perspective of the driver.

Method for generating an acoustic driving status notification for an agricultural tractor, in which a driving speed quantity which is characteristic for a current driving speed of the agricultural tractor is identified by a control unit and is compared with a preset maximum value in order to activate a transducer, arranged in a driver's station of the agricultural tractor, to generate acoustic driving speed information when it is detected that the preset maximum value has been exceeded.

A vehicle display device includes a processor, the processor being configured to acquire a deceleration state of a vehicle achieved by driver assistance and a reason for decelerating the vehicle, and cause a display to display a deceleration image indicating that the vehicle is decelerating and a reason image indicating the reason, based on the acquired deceleration state and the acquired reason.
