The braking force control device detects an impossible state where one or some of the actuators are temporarily unable to generate a negative driving force, and a predictive state where one or some of the actuators are predicted to become unable to generate a negative driving force. Every time the coasting state occurs before establishment of the impossible state and after establishment of the predictive state, the braking force control device gradually increases the negative driving force generated by the corresponding one or ones of the actuators. Even when the coasting state occurs in the impossible state, the braking force control device does not cause the corresponding one or ones of the actuators to generate a driving force. Every time the coasting state occurs after the impossible state, the braking force control device gradually decreases the negative driving force generated by the corresponding one or ones of the actuators.

An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

A system and method for efficient (e.g., economical) computing in hybrid, plug-in hybrid, and electric vehicles is disclosed. A compute manager is configured to receive and schedule compute tasks for execution on computing cores in the vehicle to increase the usage of recaptured energy that would otherwise be wasted due to battery limitations. Vehicle status information such as current battery charge level and current route may be used to determine whether compute tasks can be beneficially executed.
