A tether kill switch for a motorcycle includes a sensor module and a key. The sensor module is adapted to receive the key and includes a magnetic substrate and at least one sensor. The key is adapted to magnetically couple with the sensor module. A vehicle control system includes a tether kill switch having a sensor module including a magnetic substrate and at least one programmable sensor. A first key and a second key each include at least one unique identifier, wherein the sensor module is adapted to receive either the first key or the second key that are each adapted to magnetically couple with the sensor module. The control system also includes a control unit, wherein the programmable sensor is adapted to identify at least one of the keys by the unique identifier, and send at least one information signal to the control unit based upon the unique identifier.

A method for alertness control of a vehicle operator includes obtaining, by an apparatus, physiological status data of a person acquired using at least one sensor including at least a biosignal sensor; determining, based on at least the physiological status data, at least one alertness value being indicative of alertness level of the person; determining, by comparing the at least one alertness value to at least one alertness reference value, whether the alertness level of the person is below a threshold alertness level for operating the vehicle; and as a response to the determining that the alertness level is below the threshold alertness level, causing an output of a control signal.

A battery powered ride-on vehicle is provided that has vehicle body, a plurality of wheels, a battery dock, a battery having battery terminals that mate with battery dock terminals, an accelerator switch and an accelerator switch controller, a power line to allow current to flow between the battery dock and the accelerator switch controller, a plurality of electrical components, an electronics controller in electrical communication with the accelerator switch controller and the electrical components, a power line connecting the electronics controller with the accelerator switch controller to allow current to flow between the accelerator switch controller and the electronics controller, a timer that calculates the time between actuations of the accelerator switch, and when the time between actuations of the accelerator switch is greater than a timer threshold the accelerator switch controller prevents a release of current to the electronics controller until the accelerator switch is actuated again.

A ride-on vehicle is provided that has a speed controlled switching system. The ride-on vehicle has a vehicle body having a driver's seat, a plurality of wheels, a motor, a battery electrically connected to the motor, a direction switch assembly electrically connected between the battery and the motor, and a speed switch electrically connected between the direction switch assembly and the motor. The direction switch assembly has a forward button and a reverse button, and is proximal the driver's seat in the vehicle body. The speed switch has a high speed setting and a low speed setting and is distal the driver's seat and generally not accessible by a rider seated in the driver's seat. When the reverse button is actuated the direction switch assembly causes the voltage observed by the motor to be at the low speed setting regardless of the setting of the speed switch.

In a system for supervising the safety on a site with at least one movable object, a drowsiness detection system is arranged at the movable object for supplying data related to a drowsiness state of an operator of the movable object. A monitoring system remote from the movable object receives the drowsiness state related data and logs and/or evaluates this drowsiness state related data.

Systems and methods of stopping propulsion of an electric vehicle in an emergency situation are provided. One method includes receiving a command to stop propulsion of the electric vehicle while the electric vehicle is in motion, and in response to the command, attempting to regulate an operation of an electric motor of the electric vehicle toward a no-load operating state of the electric motor while the electric vehicle is in motion. When the operation of the electric motor is outside a prescribed range of the no-load operating state after attempting to regulate the operation of the electric motor toward the no-load operating state, the method includes causing braking of the electric motor.
