A method for controlling an internal combustion engine of a vehicle having a continuously variable transmission is disclosed. When a driven pulley speed is less than a predetermined driven pulley speed and an actual engine speed is less than an engine speed causing a driving pulley speed to be a driving pulley engagement speed: controlling the engine to increase the actual engine speed to increase the driving pulley speed to be at least the driving pulley engagement speed. When the driven pulley speed is above the predetermined driven pulley speed, the actual engine speed is greater than the engine speed causing the driving pulley speed to be the driving pulley engagement speed, and the desired engine speed is less than the engine speed causing the driving pulley speed to be the driving pulley engagement speed: controlling the engine to operate under conditions corresponding to an engine braking speed.

A braking force control device includes a target acceleration calculation unit that calculates a first target acceleration based on an acquired operation amount of an accelerator pedal, a powertrain capability acquisition unit that acquires a braking force that is generable by a powertrain, and an instruction unit that instructs generation of braking forces in the powertrain and a brake. The instruction unit is configured to, when a first braking force for achieving the first target acceleration is equal to or less than the braking force that is generable by the powertrain, instruct a controller of the powertrain to generate the first braking force, and when the first braking force is larger than the braking force that is generable by the powertrain, instruct the controller of the powertrain to generate the braking force that is generable by the powertrain.

A method for controlling an engine of a vehicle going downhill with a throttle operator in an idle position, and a driven pulley of a CVT initially having a driven pulley speed below a predetermined driven pulley speed, includes: determining a first speed, the first speed being proportional to the driven pulley speed; as the driven pulley speed increases and the driven pulley speed is below the predetermined driven pulley speed, increasing an actual engine speed as the driven pulley speed increases; the actual engine speed being an engagement speed when the driven pulley speed is the predetermined driven pulley speed; and as the driven pulley speed continues to increase and the driven pulley speed is above the predetermined driven pulley speed: controlling the engine to operate under conditions corresponding to an engine braking speed thereby causing engine braking, the engine braking speed being less than the actual engine speed.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis rearward of the cab, an axle coupled to the chassis, a battery pack having a maximum capacity, a driveline coupled to the axle, and a controller. The driveline includes an electric motor coupled to the battery pack. The controller is configured to prevent charging the battery pack beyond a charge threshold to maintain an amount of storage capacity between the charge threshold and the maximum capacity to accommodate energy generated during one or more regenerative braking events and permit charging the battery pack beyond the charge threshold up to an overcharge threshold in response to receiving an override command or a certain mode selection. The overcharge threshold is greater than the charge threshold but less than the maximum capacity.
