A control system for a vehicle includes a first vehicle system including a plurality of components and a controller. The controller monitors diagnostic data for the plurality of components of the first vehicle system and outputs a two-state status indicator for each of the components of the first vehicle system. States of the two-state status indicator include a failing state and a not failing state. A control module is configured to receive the two-state status indicator and the diagnostic data from the first vehicle system and to convert the two-state status indicator into a three-state status indicator. The three-state status indicator includes a pass state, a fail state and an indeterminate state. The control module is further configured to alter an engine operating parameter based on the three-state status indicator.

The embodiments herein provide a self-excited contact less Hybrid Electromagnetic Braking (HEB) system provided with a both Permanent Magnetic (PM) type ECB and electrically excited windings type ECB. The HEB system has an Eddy Current Brake (ECB) and a Regenerative Brake (RB) with two outer rotors and a common internal stator. The rotor assembly of the RB is coupled to the same shaft on which the ECB rotor is mounted. The RB collects an input mechanical power from the shaft to supply electrical power to ECB windings through a power electronic interface module. A controller measures the system conditions to send a control signal to the power electronic interface module to control a power flow from RB to ECB. The ECB and RB develops two braking torques on the shaft to initiate a braking action in the vehicle.

A drive-home button is provided in the dashboard of a plug-in hybrid electric vehicle (PHEV). The driver presses this button when heading home or to other predetermined destination at which charging is routinely performed. The actual route, the driving style, and other relevant vehicle/road information during the trip home are stored to build up a statistical database. During a present trip home, a highly probably route is predicted based on prior trips and an energy management profile is calculated. The commands to the internal combustion engine and the electric motor are selected to cause the vehicle's battery to be substantially discharged upon arriving at home based on actual data of energy usage by the operator of the vehicle during prior trips. By using actual data, the prediction of energy usage is more accurate allowing more complete discharge of the battery.

A hybrid electric vehicle having a discrete ratio transmission shifts according to distinct shift schedules in various operating modes. For example, different shift schedules may be used for operating with the engine off, operating with the engine running, and regenerative braking. When the vehicle transitions from one mode to another, the new shift schedule may schedule a shift that the driver would not expect. To avoid annoying the driver, a control strategy inhibits the shift until either the old strategy would also schedule a shift or a customer event occurs.

Disclosed herein are systems, methods, and computer program products for controlling acceleration of a vehicle. The methods comprising: detecting a lateral distance from a point on a trajectory of the vehicle to an object the vehicle is expected to pass when following the trajectory, the object being located off of and to a side of the trajectory and the point representing a future location of the vehicle while passing the object; comparing the lateral distance to a threshold value; selecting whether acceleration limiting is to be performed by the vehicle based on whether the lateral distance is less than the threshold value; and causing the vehicle to perform operations for autonomous driving with or without acceleration limiting based on said selecting.
