System comprising duel-fuel and after treatment for heavy-heavy duty diesel (HHDD) engines

The present invention provides up-fit after treatment technology for bringing Heavy-Heavy Duty Diesel (HHDD) engine powered vehicles into compliance with the Title 13 CCR, Part 2025 mandate (meeting 2010 criteria emission standards). It also includes a Dual Fuel system, Exhaust Thermal Management System further reducing: NOx constituents, consumption of diesel fuel, particulate matter and CO2 emissions. The invention further comprises multiple sensors that provide data to electronic control module(s). The APGV6000 enables rapid after-treatment thermal activation, compares “real-time” sensor data with target data, and adjusts the after treatment system and / or dual fuel system and / or Exhaust Thermal Management system to produce exhaust emissions well below 2010 exhaust emission standards. For 2010 and newer HHDD engine applications, the V6000 comprises the Dual Fuel and exhaust thermal management system to affect rapid after-treatment activation, reduced NOx emissions well below, 2010 (current) standards, reduce diesel fuel usage and reduce CO2 emission.

Vehicle formation driving control system and method

The invention provides a vehicle formation driving control system and method, and belongs to the field of vehicle driving control. The vehicle formation driving control system comprises a head vehicle and at least one rear vehicle. The head vehicle and the rear vehicles are provided with fleet queue control terminals and whole-vehicle controllers. The whole-vehicle controllers control the driving states of the vehicles. The fleet queue control terminals are connected with the whole-vehicle controllers through CAN buses. Each fleet queue control terminal comprises a wireless communication module used for mutual communication among the head vehicle and the rear vehicles; a distance detecting module used for detecting the distance between the vehicle and a front vehicle; a positioning module used for obtaining the real-time information position of itself; and a lane information obtaining module used for obtaining lane information. The vehicle formation driving control system and method maintain the stability of a fleet, enhance the driving safety and help fleet members successfully and rapidly reach destinations respectively; in addition, the system and method are simple and effective, the scheme is mature, the oil consumption can be reduced by as much as 50%, and the frequency of traffic accidents is effectively lowered.

Regional path tracking control method for autonomous land vehicle

The invention discloses a regional path tracking control method for an autonomous land vehicle. A problem that collision of a vehicle with a road boundary or surround obstacle occurs because shapes and sizes of the vehicle and the road are not considered by the existing tracking control method can be solved. The method comprises the following steps: establishing a two-dimensional road model; establishing a mathematical model associated with a vehicle path tracking problem; calculating a roadable region boundary line within a certain distance in front of the vehicle; establishing a vehicle system model; carrying out a design of a regional path tracking control model and selecting a controlled quantity being an optimum front wheel steering angle at current time; according to the optimum front wheel steering angle, controlling a steering execution mechanism to make motion to enable the controlled vehicle to be driven in a roadable region, provided by a vehicle sensing system, within a certain distance in front of the vehicle. When the two-dimensional road model is established, the shapes and sizes of the vehicle and roads are taken into consideration, thereby reducing the possibility of collision of the vechile with the road boundary and thus improving safety of the autonomous land vehicle.
