If the maximum speed differential between the vehicles was 15 km/h, a rear-end collision would be avoided in most cases. And, at greater relative speeds, the severity of the impact would be considerably mitigated. At the same time, the City Safety system optimizes occupant protection by providing additional data to the airbag control unit and triggering the restraint systems as required. Like the front and side airbag initiation sensors, this is also a Continental product. According to Dr. Ralf Cramer, President of the Chassis & Safety Division, "This system will prevent numerous accidents and injuries. It is one of the important modules in our comprehensive ContiGuard(R) safety system which is bringing us one step closer to Vision Zero, our vision of road transport without accidents, without serious injuries and without fatalities."
MK25 E1 braking system with trailer stabilization and roll-over protection functions
Even if the braking system does not intervene automatically, Continental's CV sensor system can assist the XC60 driver. If he realizes that a rear-end collision is imminent and applies the brakes, the MK25 E1 will already have built up pressure as a precaution. The brake assist system will respond earlier, depending on how risky the situation is, shortening the stopping distance more effectively than would be possible without the CV sensor's warning.
In addition to this interface to the environmental sensors, the braking system also has a trailer stabilization function which detects if a trailer is beginning to "fishtail" and stabilizes the car-trailer combination by brake application to individual wheels (Trailer Stability Assist, TSA). A further driving safety feature is the roll-over protection function. As well as the usual ESC sensors, the Volvo XC60's braking system has an additional sensor which records the vehicle body's rolling motion. If all the data it collects indicates that the vehicle is seriously at risk of overturning, the brakes are specifically applied to individual wheels. This roll sensor is built into the ESC cluster which, like the active wheel speed sensors, the brake actuation unit and the new two-piston, front axle, 2FN44 wheel brakes, is also supplied by Continental's Chassis & Safety Division.
Drive system, tires, access authorization: Continental's comfort, safety and security products
Continental also supplies the vehicle's tire pressure monitoring system, ContiCrossContact UHP 235/65 R17 V and 235/60 R 18 tires and the electronic control unit for the intelligent all-wheel drive. The latter ensures the optimum distribution of torque between the front and rear axles according to the driving situation.
Security and comfort benefit in equal measure from the optional keyless Personal Car Communicator (PCC) access authorization system. Continental produces several main components of the radio-controlled system of the Volvo XC60, from the key to the transceiver built into the vehicle. At the touch of a button, an XC60 driver can check whether his car is actually locked from a distance of up to 100 meters. Continental has been working with Volvo for years and produces main components of the radio-controlled system for the current S80, V70 and XC70.
With targeted annual sales of more than euro 26.4 billion for 2008, the Continental Corporation is one of the top automotive suppliers worldwide. As a supplier of brake systems, systems and components for the powertrain and chassis, instrumentation, infotainment solutions, vehicle electronics, tires and technical elastomers, the corporation contributes towards enhanced driving safety and protection of the global climate. Continental is also a competent partner in networked automobile communication. Today, the corporation employs approximately 150,000 people at nearly 200 locations in 36 countries.
As a worldwide leading technology and systems partner to the automotive industry, the Chassis & Safety Division of Continental AG integrates extensive know-how and leading-edge quality in the fields of active and passive driving safety, safety and chassis sensorics, and chassis components. The Division achieves sales of more than euro 5 billion (based on 2006 figures) with a workforce of more than 27,500 (2007). Chassis & Safety develops and produces electronic and hydraulic brake and chassis control systems, sensors, driver assistance systems, air bag control systems, occupant classification systems, washer systems as well as electronic air suspension systems.
