The present application describes systems and methods for detecting more than a predetermined number of riders on a vehicle. Embodiments may either infer or directly measure the mass of the user and the vehicle using one or more sensors on the vehicle to calculate the mass using a microprocessor coupled to the one or more sensors. The system and methods may take various steps to encourage riders to dismount the vehicle if the total number of riders, determined by weight, exceeds the allowed number.

Presented are intelligent vehicle systems for thermal event mitigation during vehicle towing, methods for making/using such systems, and vehicles equipped with such intelligent control systems. A method of operating a host vehicle includes a resident or remote vehicle controller verifying the host vehicle is an incapacitated state. Responsive to the incapacitation of the host vehicle, the controller detects the host vehicle being towed by a tow vehicle and identifies a wireless-enabled portable computing device (PCD) within a predefined range of the host vehicle. Responsive to the host vehicle being towed, the controller determines if the wireless-enabled PCD is on the tow vehicle while towing the host vehicle. Upon detection of a thermal event in at least one battery cell in the host vehicle's battery system while the host vehicle is being towed, the controller responsively commands a resident vehicle subsystem to execute a control operation to mitigate the thermal event.
