This invention involves the effect of multiple rules of the road at different elevation profiles on the speed constraints and therefore the overall fuel efficiency. A vehicle designed to optimize fuel consumption that is comprised of the rules of the road that determine maximum speed, minimum speed, stop signs, streetlights, and/or changes in other rules that determine the allowable speeds of the road, a localization mechanism, and an optimization engine to optimize the fuel economy by selecting a speed profile within that maintains the vehicle within the assigned range of speeds and minimizes fuel consumption. A wide variety of methods that typically are used to optimize the fuel efficiency of human drivers operating standard vehicles can also be applied towards autonomous vehicles driving at different speed constraints and with different changes in the elevation.

A method of estimating a load on a vehicle (10), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

The present disclosure relates to a method for a torque control of a hybrid vehicle, a storage medium and an electronic device. The method includes: determining a target-total-torque-change-gradient when a limitation requirement for a gradient of torque change of a DCT is received; determining a torque request of an electric motor and an actual-torque-response-change-gradient of an engine; and determining a gradient of torque change of the electric motor according to the target-total-torque-change-gradient and the actual-torque-response-change-gradient of the engine; and filtering the torque request of the electric motor according to the gradient of torque change of the electric motor. The limitation of the gradient of torque change of the DCT is considered, A problem that the actual total torque responses of the electric motor and the engine exceeds the limitation requirement of the gradient of torque change of the DCT is effectively solved, and a drivability of the whole vehicle is improved.

Systems and methods for detecting and issuing one or more safety measures if a person or an object has separated from a moving vehicle. The system may include at least one torque sensor coupled to the vehicle and configured to detect torque at a drivetrain of the vehicle. The system may further include at least one processor in electronic communication with the at least one torque sensor. The at least one processor may be configured to measure change in torque in real-time, where the change in time is directly proportional to a change in a mass of a load carried by the vehicle. The system may further include an alerting device controlled by the at least one processor. The alerting device may be configured to alert an operator of the vehicle when the change in torque exceeds a predetermined threshold value.
