A method for monitoring the environment of a vehicle includes evaluating physical measurement data obtained from the environment of the vehicle to determine whether at least one person is approaching the vehicle, how many people approach the vehicle may also be recorded. The method includes evaluating physical measurement data obtained from the environment of the vehicle to determine whether at least one person is moving away from the vehicle and, if appropriate, the number of people that are moving away from the vehicle is also recorded. The method further includes carrying out a check as to whether the number of people that have moved away from the vehicle corresponds to the number of people that have previously approached the vehicle. In response to the check resulting in a difference, it is determined that the vehicle is in an unsafe state.

A side-by-side off-road utility vehicle comprising a vehicle operational status switch for controlling the operational status of the vehicle, a side-by-side seating structure, a plurality of safety restraint devices operable to retain one or more vehicle passenger in the side-by-side seating structure, and a prime mover RPM controller. The prime mover RPM controller operable to output commands to the one or more prime mover of the vehicle to limit a rotational speed of the prime mover(s) when the vehicle is in an On operational status and a selected one or more of the one or more safety restraints is in a disengaged status.

A movable carrier auxiliary system includes a driver state detecting device and a warning device. The driver state detecting device includes a physiological state detecting module, a storage module, and an operation module. The physiological state detecting module is adapted to detect a physiological state of a driver. The storage module is disposed in a movable carrier and stores an allowable parameter corresponding to the at least one physiological state. The operation module is disposed in the movable carrier and is electrically connected to the physiological state detecting module and the storage module to detect whether the at least one physiological state of the driver exceeds the allowable parameter or not, and to correspondingly generate a detection signal. The warning device generate a warning message when the detection signal that the at least one physiological state of the driver exceeds the allowable parameter is received.

Systems and methods preventing vehicle runaway of an electric powersport vehicle in an emergency situation are provided. One method comprises receiving, via an emergency shutoff switch of the electric powersport vehicle or via a tether switch of the electric powersport vehicle, a signal indicating an existence of the emergency situation while the electric powersport vehicle is in motion, and in response to the signal, attempting to regulate an operation of an electric motor configured to propel the electric powersport vehicle to cause regenerative braking of the electric motor while the electric powersport vehicle is in motion.

A lane detection system for a vehicle includes at least one sensor for sensing lane markers and objects in the vicinity of a host vehicle, a driver interface in the host vehicle, and a controller having control logic. The control logic receives signals from the at least one sensor, determines a present lane of travel based on the sensor signals received, determines that a time that the host vehicle has been in the present lane of travel meets or exceeds a predetermined time, and transmits an alert signal to the driver interface in response to the time meeting or exceeding the predetermined time.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

A sudden acceleration prevention method for a vehicle includes the following steps, which may be performed by a controller: monitoring an output signal of an accelerator pedal sensor so as to obtain a detected operation state of an accelerator pedal, determining whether the detected operation state of the accelerator pedal is within a predetermined brake pedal operation range, determining whether the detected operation state of the accelerator pedal is within a predetermined accelerator pedal and brake pedal overlapping operation range if the detected operation state of the accelerator pedal is within the predetermined brake pedal operation range, and outputting an output reduction control signal of the vehicle if the detected operation state of the accelerator pedal is not within the accelerator pedal and brake pedal overlapping operation range.
