In this paper, we introduce a novel Physical layer Assisted message Authentication (PAA) under public key infrastructure (PKI) in vehicular communication networks. The novel authentication scheme takes advantage of temporal and spatial uniqueness in physical layer channel responses for each transmission pair, in which a trust between two vehicles can be maintained by comparing the current estimated channel response and the previous estimated channel response. We will show that the proposed message authentication scheme can achieve extremely high efficiency and minimal authentication delay without compromising the security requirements, which is further verified through both analysis and simulation.

Many fuel consumption improvements for heavy-duty diesel engines have been achieved in the area of control and calibration. Few have addressed methods of improving fuel consumption during highway cruising. Since cruise control is activated most of the time during long trips, it should be seen as a viable option for improving fuel economy. If environmental changes and resulting engine load changes can be anticipated, the cruise control operation can be optimized with respect to fuel efficiency. We propose three cruise control reference-shaping strategies to improve engine efficiency and reduce truck on-highway cruising fuel consumption. These strategies would use GPS and computerized terrain maps to predict upcoming engine load changes in order to improve fuel economy. Assumptions are identified and appropriate constraints imposed on the fuel consumption, vehicle speed and nominal mission time. The algorithms of the three shaping strategies predict torque in order to prevent engine lug back and improve fuel economy. The algorithms were tested using a Matlab simulation on five routes. On average over the routes, fuel improvement of 1.77% was achieved.

The new control algorithm combining LQG and Fuzzy logic controller (LFLC) adapted to vehicle speed and road conditions is proposed to compromise the classical suspension conflict between ride comfort, handling and packaging requirements. Tracking the signals of the suspension working space and body acceleration that vary sharply with the variation of road conditions and vehicle speed, LFLC can regulate the weights of the performance indexes dynamically to schedule the gain of the LQG controller for achieving multiple control objectives. Compared with the passive suspension and the conventional LQG control system, the simulation results demonstrate that LFLC can improve effectively the ride comfort and safe drivability at different speeds or road conditions without violating the given suspension deflection limit.

In this paper, a motion follow controller for a 4-wheel-drive electric vehicle based on one track non-linear vehicle model and variable structure control (VSC) theory was designed. Combining the controller with optimal control allocation algorithm which takes into account of longitudinal/lateral force couple characteristic for tire under critical situation, we designed the vehicle stability control system. By using veDYNA, the double lane change simulation was carried out to verify the validity of control method. The results of simulation show the proposed control method could stabilize vehicle well under critical situation. The reference model plays an important role at stabilizing vehicle attitude, but inevitably alters the steering characteristic, which brings certain conservative. Actual control allocation could match the general requirement well by taking into account of tire force characteristic.

This paper studies the car-following behaviors of individual drivers in real traffic scenes using the trajectory datasets provided by Next Generation SIMulation (NGSIM) program. We calibrate Intelligent Driver Model (IDM) and MIcroscopic Traffic SIMulator (MITSIM) car-following models by using Genetic Algorithm (GA), with a special emphasize on MITSIM model, because there are already some nice works on the calibration of IDM model. We find that after calibration, the tracking gap errors of both models are normally below 30%. We also find that the parameter set (α+, β+, γ+, α−, β−, γ−) of MITSIM model obtained from different sampling trajectories roughly locate in a low-dimensional hyperplane rather than randomly distribute in the entire parameter space.

This paper is based on the hybrid braking system, in which the hydraulic braking system is adjustable. In the paper a braking torque dynamic distributor is designed so that the output torque can track the input torque accurately. Meanwhile a sliding mode controller is constructed, in which the slip ratio value doesn't perform as the main control parameter. Accordingly, the total torque is regulated in order to prevent the skidding of the wheel. Then the braking safety is guaranteed.

This work presents a receiving module consisted of a CMOS low-noise amplifier (LNA) followed by a semi-lumped filter and a CPW-fed slot dipole antenna, both circuits are connected using low-cost bonding wires. The structure of the receiver is realized with antenna-in-package (AiP) concept, which reduces the antenna interference through the substrate to the other radio front-end (RF) circuits on the same substrate. To enlarge input impedance bandwidth of the antenna, the dipole arms are constructed with bow shape. Two-stage cascode LNA operated at 11.6 GHz is employed to provide adequate reverse isolation and power gain. For X-band applications, experimental results prove that the operation bandwidth and transmission gain of the receiving module are dominated by the input impedance bandwidth of the antenna rather than the effect of the bonding wires. Measured data of the wireless communication link shows a transmission gain of 12 dB from 10.5 to 14.5 GHz.
