Some combustion engine vehicles report a negative torque under braking conditions. This cannot be properly reflected by the current definition of engine torque as it is an unsigned integer. This change proposes modifying the combustion engine torque definition from an unsigned integer to an integer. Signed-off-by: Pierre Pierre Blais <[email protected]>
