Siemens VDO Automotive presents an ergonomic network of driver assistance systems at the 61st IAA Motor Show in Frankfurt, Germany.
Siemens VDO Automotive is integrating a night vision system in the head-up display to effectively support nighttime driving in the future. With infrared technology and high-performance electronics, it literally provides vision in the dark and under poor visibility conditions, helping drivers to spot pedestrians and other potential accident hazards on the road. The result is a considerable increase in safety at night when many accidents occur. Night Vision is one of the functionalities within a network of driver assistance systems that Siemens VDO is currently developing.
Is this mean even i switch off my car light at night, i still can drive like day time just looking the at the my LCD mirror??Is NightRider not KnightRider…

At the 61st IAA Motor Show in Frankfurt Siemens VDO 
Automotive is exhibiting future braking technology with the electronic wedge brake, which will enable the launch of brake-by-wire series production for the 12-volt vehicle electrical system in this decade. The modern wedge brake offers considerable safety and comfort advantages over the hydraulic brake.
Here how it work…
When the driver engages the brake pedal, the EWB system electronically transmits the activation signal to the interconnected brake modules. When the brake activation signal is received, electric motors actuate a wedge-bearing mechanism consisting of several rollers to move the wedge into the required position according to the sensor feedback values. This causes the brake pad to be pressed against the brake disk. Based on the principle of self-energization, the braking effect builds up very rapidly and the intelligent control prevents any danger of the wedge blocking. This principle of “unstable” control structures was taken from high safety-critical systems for aviation and aerospace applications and adapted for automotive purposes.
The EWB eliminates the need for components such as hydraulic pipes, brake cylinders, brake boosters or antilock braking control units. This lowers overall weight and makes for greater reliability for improved safety, with reduced servicing requirements. By doing away with the hydraulic braking system, it also helps to reduce the vehicle’s environmental impact.
But when it come to electronic component of car, safety is alway the concern just like airbag.What if the electronic device suddenly mulfunction, or the battery supply shortage… Can you have a backup plan…
According to Sieman it need to take decade to apply this technology to all car in future…
